Diagnostic & Lab Report Error Consumer Complaint Puducherry

Common Grievances

• Sample mix-up: Results reported for the wrong patient, or a sample mishandled/contaminated before testing.
• False positive/negative results: A materially wrong result not attributable to inherent test limitations, leading to wrong treatment or a missed diagnosis.
• Reporting errors: Correct test performed but wrongly transcribed/reported (wrong units, decimal errors, wrong reference range applied).
• Improper collection/storage: Sample collected or stored in a manner inconsistent with the test's requirements, affecting result accuracy.
• Unaccredited/unqualified testing: Tests performed without appropriate accreditation (e.g. NABL — National Accreditation Board for Testing and Calibration Laboratories) or by unqualified personnel, where this is directly relevant to a reporting error.

Applicable Law

A diagnostic centre/pathology lab providing testing services for consideration is a "service" provider under Section 2(42), CPA 2019, and the patient is a "consumer" under Section 2(7). As with other medical services, following Indian Medical Association v. V.P. Shantha, (1995) 6 SCC 651, diagnostic services rendered for consideration fall within the Act's scope. A report that is inaccurate due to a lapse in the lab's process (sample handling, testing procedure, or reporting) — falling below the standard reasonably expected of a competent lab — is "deficiency" under Section 2(11). Where NABL accreditation was represented but the lab was not actually accredited, or testing did not follow the lab's own accredited protocol, this is relevant evidence of the lapse and can separately amount to "unfair trade practice" under Section 2(47).

Jurisdiction & Forum

(Section 34(1)/47(1)(a)(i)/58(1)(a)(i) of the Act itself set these thresholds at ₹1 Crore / ₹10 Crore / above ₹10 Crore; each carries a proviso letting the Central Government prescribe a different value. Exercising that power, the Consumer Protection (Jurisdiction of the District Commission, the State Commission and the National Commission) Rules, 2021 currently set the values shown in the table above.) A Puducherry patient may generally file at DCDRC Puducherry under Section 34(2). Note again that jurisdiction is based on the value of consideration paid for the test, not the compensation sought for resulting harm — assess the appropriate forum on the facts.

Limitation Period

Under Section 69, CPA 2019, a complaint must ordinarily be filed within two years from the date the cause of action arose — generally the date the reporting error was discovered (which may be later than the date the report was issued, especially where the error only becomes apparent after a repeat/confirmatory test).

Documents Typically Needed

• The disputed test report, and the doctor's prescription/referral for the test
• Any repeat/confirmatory test report showing the discrepancy
• Treatment records showing what treatment was given based on the erroneous report
• The lab's accreditation status (NABL or otherwise), if relevant to the claim
• Independent expert opinion on the reporting error and its cause, where available
• Correspondence with the lab/diagnostic centre regarding the error

General Process Outline

1. Step 1 — Written complaint: Report the discrepancy to the lab/diagnostic centre in writing, with the confirmatory/repeat test result.
2. Step 2 — Independent expert opinion (recommended): Obtain an independent opinion on the reporting error, particularly where causation of harm is in dispute.
3. Step 3 — Legal notice: A written notice to the lab/diagnostic centre setting out the error and relief sought.
4. Step 4 — File the complaint: Under Section 35, with supporting documents, at the appropriate forum by claim value, online via e-jagriti.gov.in or in person; it is heard on the basis of an affidavit and documentary evidence (Section 38(6)).
5. Step 5 — Admission, evidence, hearing: Per Section 36 (admission, ordinarily within 21 days of filing) and Section 38 (notice to the opposite party within 21 days of admission; response within 30 days, extendable by 15 days), then hearing, generally with expert evidence on the standard of testing/reporting and how it was not met.
6. Step 6 — Order: Under Section 39, the Commission may direct relief it considers appropriate on the facts proved; the Act does not fix or guarantee any specific outcome.
