CAN A DIAGNOSTIC LAB BE SUED UNDER CONSUMER LAW FOR GIVING A FALSE MEDICAL REPORT?

ABSTRACT

Every year, millions of patients depend on the reports generated by diagnostic labs in India. The consequences of a false positive medical report, a report that mistakenly states there is a disease or condition when actually there is not, can be: unnecessary surgical procedures, extended medication courses, extremely stressful psychological experiences, and financial losses. The question that this article is designed to answer is basic: Can a patient who suffers from a diagnostic error have a claim of consumer protection?

This article answers that question in a resounding yes. With detailed analysis of subsequent Supreme Court and National Consumer Disputes Redressal Commission (NCDRC) judgments, it establishes that diagnostic laboratories are ‘service providers’ under the Act, patients are ‘consumers’ and that a negligently furnished false report amounts to a ‘deficiency in service’ under which actionable liability can be claimed.

INTRODUCTION

Having a correct medical diagnosis is not just an expectation when receiving care; it is a legal right. Being told that you are HIV-positive when you are not or that you have cancer when you do not is devastating. The patient might lose their job, may have to go through invasive medical treatments, may have relationships that will be destroyed, and may experience unknown mental anguish, all because of a wrongful report.

The Consumer Protection Act, 2019, enacted in India, has a very strong mechanism to provide relief to such scenarios. The Act removed the limitation which only permitted ‘defects in goods’ to be pursued: it explicitly includes ‘deficiency in services’, diagnostic testing being one of them. The patient pays a fee, the lab agrees to do the test correctly, and the negligently done test is a textbook deficiency.

The three questions this article seeks to answer are:

Are diagnostic laboratories in the consumer protection arena?
What is the role of consumer protection in diagnostics?
What is the role of diagnostic laboratories in consumer protection?
The standard of care expected and what constitutes negligence in reporting?
Remedies if the patient is aggrieved and limits of liability.

LEGAL FRAMEWORK

A. The Consumer Protection Act, 2019, includes the following key provisions:

The Consumer Protection Act, 1986, was replaced by the Consumer Protection Act, 2019 (‘the Act’ or ‘CPA 2019’). It entered into force on 20 July 2020 and greatly enhanced the rights of the consumer. The following statutory provisions have a specific relevance:

Section 2(7) — ‘Consumer’: A person who hires or avails of any ‘service’ for consideration. A patient who pays a diagnostic lab for a blood test or scan is unambiguously a consumer.
Section 2(42) — ‘Service’: Defined very broadly to mean service of any description made available to potential users, expressly including medical and health services. Diagnostic testing squarely falls within this definition.
Section 2(11) — ‘Deficiency’: Any fault, imperfection, shortcoming, or inadequacy in the quality, nature, or manner of performance of a service. A false positive report — issued due to improper calibration of equipment, lack of trained staff, or procedural error — is a deficiency.
Section 2(35) — ‘Unfair Trade Practice’: Includes any practice which, for the purpose of promoting a service, makes a false statement. Systemic over-reporting of positive results to generate follow-up revenue can constitute an unfair trade practice.
Section 38 — Complaint before District Commission: A consumer may file a complaint before the District Consumer Disputes Redressal Commission for claims up to Rs. 1 crore.
Section 47 — State Commission: Jurisdiction over complaints where value exceeds Rs. 1 crore and up to Rs. 10 crore.
Section 58 — National Commission (NCDRC): Jurisdiction over complaints exceeding Rs. 10 crore and appellate jurisdiction over State Commission orders.

B. The Constitutional Foundation

India’s Constitution provides for the right to life and personal liberty under Article 21. In Paschim Banga Khet Mazdoor Samity v. State of West Bengal, the Supreme Court did not doubt that the right to health and the right to receive accurate medical information are part of this fundamental right. The right of a patient under Article 21 is directly violated by a false result from a diagnostic lab, which leads to unnecessary surgery.

C. Some obligations of a diagnostic laboratory according to the law.

In addition to the CPA 2019, there are multiple instruments which regulate the diagnostic laboratories in India:

The Clinical Establishments (Registration and Regulation) Act, 2010: Sets minimum standards of facilities, equipment and qualified personnel in clinical establishments, including diagnostic laboratories. Failure to comply evidences negligence.
Bureau of Indian Standards (BIS) – IS 15189 – Indian standard for quality and competence of medical laboratories. Failure to adhere to the requirements is acceptable as proof of inadequate care.
Indian Medical Council (Professional Conduct, Etiquette and Ethics) Regulations, 2002: Lay down the responsibilities of the laboratories for the accurate results and proper calibration of laboratory equipment. Violation of these rules enhances a negligence claim.
Drugs and Cosmetics Act, 1940 (Amended): Applies to reagents and diagnostic kits used in laboratories. The use of an outdated or inadequate reagent that gives a false result is a violation of regulations and a sign of negligence.

CASE STUDIES

A. The ruling of the Foundational V.P. Shantha (1995/1996)

The most significant case in this regard is:

Indian Medical Association v. V.P. Shantha & Ors.

Facts: The Indian Medical Association raised the issue of the applicability of the Consumer Protection Act, 1986, to medical services, arguing that a doctor-patient relationship was a professional relationship, and not a commercial service.

Held: Supreme Court (3-Judge Bench) held that the medical services that are rendered by a doctor or a hospital for consideration are clearly within the ambit of ‘service’ under the Consumer Protection Act. The Court rejected the argument which contended that professional services were exempt. The judgment paved the way for all medical service providers, such as diagnostic laboratories, to be subject to consumer forums.

The V.P. Shantha ruling has been the backbone of all consumer complaints against diagnostic laboratories in the years that have followed. So, after this judgment, there was no legal basis for a lab to say the consumer forum had no jurisdiction over it.

B. Standard of Care: What is ‘Negligence’ for a Diagnostic Lab?

Achutrao Haribhau Khodwa & Anr. v. State of Maharashtra

Facts: A doctor left a mop in a patient’s abdomen during surgery, which caused her to die. The question was the standard of care that is expected by medical professionals.

Held: A medical practitioner must exercise the ordinary skill of a medical man who professes to do that job. Specialist skills are required, and must be used, where appropriate. The standard is not perfection; it’s the standard of a reasonably competent person in that profession. The same ‘Bolam test’ (taken from English law) is applicable to diagnostic laboratories.

Applying Achutrao to diagnostic labs: A laboratory should have calibrated equipment, utilise validated reagents, employ qualified pathologists and technicians, adhere to standard operating procedures, and double-check borderline results. The negligence standard is satisfied if there is a failure in any of these links, because a false positive will result.

Jacob Mathew v. State of Punjab & Anr.

The facts: A hospital discovered an empty oxygen cylinder and a patient died. There was a question of whether medical negligence could be a criminal responsibility.

Held: Supreme Court pointed out an important difference between civil negligence (departure from accepted standards resulting in harm) and criminal negligence (gross, reckless or wanton departure). Civil negligence is adequate for consumer law. The CPA 2019 states that failure to perform basic quality protocols in a laboratory leads to a false diagnosis, it is considered to be in breach of the civil negligence standard.

C. The diagnostic laboratories are responsible for the fees paid for their services- Direct Liability of Diagnostic Laboratories

Cosmopolitan Hospitals & Anr. v. Vasantha P. Nair

Facts: The complainant had been taken to the hospital by the respondent for a biopsy, which had been reported as a malignant tumour, and a diagnosis made on this basis led to the complainant being operated upon. Tissue from the surgery was found to be non-cancerous. The patient had an unnecessary mastectomy done.

Issued: The NCDRC pointed out that it was a serious lack of service to issue an incorrect biopsy report. The hospital was found liable for the patient’s physical and psychological injury as a result of the unnecessary surgery. Medical costs, pain and suffering, and mental anguish were all paid.

Pravat Kumar Mukherjee v. Ruby General Hospital & Ors.

The facts in this case are that the complainant’s wife was misdiagnosed, and improper treatment was provided. The diagnostic unit at the hospital didn’t adhere to standard procedure.

Reiterated: The National Commission restated that the duty of care is not delegable from hospitals and from their diagnostic wings to the patients. It is not an error of judgment, but a failure of service to which liability can be attached under the Consumer Protection Act if an error is traced to failure to follow the protocol, inadequate equipment maintenance, or lack of trained staff.

Dr. Balram Prasad vs Dr. Kunal Saha & Ors.

Facts: An individual died because of negligence by a medical professional. There was a long dispute over the quantum of compensation, which included compensation for loss of future earning capacity, pain and suffering and cost of treatment.

Granted: The Supreme Court gave the money to him. The compensation of Rs. 1.55 crore is the highest given in India and set a precedent in calculating compensation in medical negligence cases. The Court ruled that the compensation should be adequate, fair and reasonable, it should cover medical bills, loss of income, mental anguish and out-of-pocket expenses. This framework explicitly applies to victims who are falsely identified.

Harnam Singh vs Sushil Sharma and others.

Petitioner’s representation was rejected, and the complaint filed by the Petitioner was dismissed for being out of time.

Facts: A diagnostic laboratory gave the complainant a false positive report indicating that she had syphilis. The complainant was sacked from his employment, his marriage was broken off, and he faced great social disapproval based on this report.

Held: The State Commission was satisfied that the laboratory was guilty of a deficiency in service and granted compensation for financial loss, mental agony and social humiliation suffered by the claimant due to the false report. The Commission noted that a laboratory report is not a casual document; it has a significant impact on a patient’s life and has a legal force because accuracy is a duty that is owed.

D. The Three-Stage Test: Was the Lab Negligent?

From a review of the case law, a consumer forum will conduct 3 enquiries to establish the liability:

STAGE 1: Duty of Care — Was the complainant owed a duty of care by the lab?

Answer: Always yes – the service is provided by the lab and the patient pays for this. This is supported by the V.P. Shantha ruling and the CPA 2019.

STAGE 2: Breach of Standard: Was the laboratory not performing at the level of a reasonably competent diagnostic laboratory? This is demonstrated by:

(a) using expired or substandard reagents;

(b) not repeating a borderline result;

(d) a report by an unqualified person; or

(e) not marking a result for second opinion.

STAGE 3: Causation and Harm: Was there an actual loss for the patient? There must be evidence that the false report caused the patient’s actual harm (unnecessary surgery, wrong drug treatment, loss of a job, psychological trauma, etc.) and not just some other cause.

CRITICAL ANALYSIS AND A WAY FORWARD

A. Regulatory Gaps — The Enforcement Problem.

The legal system is clear but not equal. There are more than 100,000 diagnostic labs in India, but not all states have yet implemented the Clinical Establishments Act. In states that do not have a minimum quality standard, laboratories operate without such quality requirements, allowing for easier operation of substandard facilities. This regulatory vacuum leaves weaker administrative remedies for patients in non-adopting states and only a consumer forum.

In addition, quality accreditation through NABL (National Accreditation Board for Testing and Calibration Laboratories) is voluntary. A few laboratories are accredited by NABL. Courts have mentioned NABL accreditation as being proof of meeting the standards, thus establishing a dual pathway whereby accredited labs are presumed to be more defensible.

B. The ‘Error of Judgment’ Defence – its limits and critique

Diagnostic laboratories typically argue that a positive test was an ‘error of judgment,’ and not a failure of care, using the distinction between a bona fide clinical error and negligence that Jacob Mathew made. This defence has been met with criticism by courts in the diagnostic setting. A diagnostic laboratory does not use independent clinical judgment but follows a certain procedure. In conducting an ELISA test or in preparing a blood smear, there is not much space for ‘judgment’. When following the protocols and the equipment is operating properly, false positives can be expected to be quite uncommon. If you have a false positive in a well-performed lab, you are more likely to have another test than you are if you have a final report.

The NCDRC and various High Courts have then decided that the error of judgment defence is applicable in the clinical diagnosis context, but is limited in the diagnostic lab context. It is the responsibility of the lab to demonstrate what protocol it used and how its result was a reasonable outcome of that protocol.

C. Compensation — What Can the Patient Claim?

Based on the CPA 2019 and Dr. Balram Prasad, a false-positive victim can receive the following heads of compensation:

Medical Expenses: Cost of the wrong test, cost of confirmatory test(s) taken elsewhere and cost of any treatment (surgery, medicine) that was carried out based on the false report.
Where the patient lost income as a result of hospitalisation, incapacity, or loss of job which resulted from the false report (e.g., HIV or cancer false positive).
Mental Agony and Psychological Harm: Given regularly by consumer fora. A false positive for cancer or HIV is recognised as a compensable harm in and of itself.
Social Stigma and Relationship Loss: As seen in Harnam Singh, social and relational consequences that directly stem from the false report, e.g. cancelled marriages, social ostracism, are compensated as well.
Litigation Costs: Consumer fora routinely award litigation costs.
Punitive / Exemplary Compensation: Section 39(1)(d) of the CPA 2019 provides fora with the power to award punitive damages in case of a gross, systematic or disregard of consumer rights in the case of a deficiency.

D. Proposed Reforms

The following reforms would improve the safeguarding of patients from erroneous diagnostic reports:

Use of NABL Accreditation should be mandatory, and be audited periodically for all labs used for clinical samples. This would solve the quality issue of two levels.
Repeat testing for life-altering diseases should be required in such instances: If the test is positive for a life-altering disease (HIV, cancer, hepatitis), then the result should be repeated using a new specimen from the same patient before the final report is given.
Compulsory Insurance: Diagnostic labs should be mandated to have medical indemnity insurance; to ensure that if there is any compensation awarded by consumer fora, it is actually paid to the patient.
Digital Report Integrity: All test results, from sample collection to final report, should be captured in a digital audit trail, which would make it difficult to manipulate results and easy to determine how the lab performed the tests in case of litigation.

CONCLUSION

Indeed, it is clear that a diagnostic laboratory may, and should, be held liable under consumer law for providing a false positive medical report that results in harm to the patient.

There is a comprehensive framework provided in the Consumer Protection Act 2019. A patient is a customer. A diagnostic test is a service. A false positive due to negligence (e.g., by reason of equipment failure, failure of the protocol, or failure of the person performing the test) is a lack of service. The three-stage duty, breach and causation inquiry, as well as the jurisdictional framework provided by V.P. Shantha and the standard of care by Achutrao, is well established from case law.

In these cases, the courts have not backed down from the awarding of significant compensation: wrongful testing goes beyond the financial implications. It penetrates to the patient’s body, mind, relationships and livelihood. Each of these dimensions is understood and addressed by the law, if correctly interpreted and applied.

The rest of the challenge is structural and regulatory: compulsory quality accreditation, compulsory repeat testing for life-changing diagnoses, and compulsory insurance; all would turn the consumer protection regime from a reactive remedy to a proactive safeguard. At present, the only available and best way to handle a patient who is misled by a bogus diagnosis is to go through a consumer forum before any reforms are implemented.
