Lab Report Format in India: What to Print and Who Must Sign

Quick answer: a pathology lab report in India should show the lab's name, address and registration or accreditation details, the patient's name, age, sex and ID, the referring doctor, a sample ID, when the sample was collected, received and reported, and for each test the result, unit, reference range and a flag for abnormal values. It must be signed by a registered medical practitioner with a postgraduate qualification in the relevant subject — a pathologist for pathology reports.

This guide gives you a ready lab report format, explains who may sign a report, and lists the mistakes that send patients back to the lab.

What every lab report should show

Section	What to include
Header	Lab name, address, phone, and registration or NABL accreditation number if you have one
Patient	Name, age, sex, phone and patient ID or registration number
Referral	Referring doctor ("Ref. by"), or Self
Sample	Sample ID or barcode number, sample type (blood, serum, urine), and the collected, received and reported date and time
Results	Department heading (Haematology, Biochemistry…), then for each test: test name, result, unit and biological reference range
Flags	High (H), Low (L) or critical values marked so the doctor sees them at once
Notes	Method where it matters, interpretation or comments, and "end of report"
Sign-off	Name, qualification, registration number and signature of the person who checked the report, and of the pathologist
Footer	A short disclaimer, page numbers on long reports, and the patient block repeated on every page so a loose sheet can still be identified

Who can sign a lab report

• In December 2017, the Supreme Court upheld the Medical Council of India's position that a laboratory report can be signed or countersigned only by a registered medical practitioner with a postgraduate qualification in pathology. A technician cannot issue a report on their own.
• The MCI's Board of Governors clarified in April 2019 that each specialist signs reports in their own field: a pathologist for pathology, a microbiologist for microbiology and a biochemist for biochemistry.
• Labs registered under the Clinical Establishments Act must also meet the minimum standards for their category, and your state may have its own rules. Check with your state's clinical establishments authority.

Mistakes that send patients back to the lab

1. No unit or reference range, so the doctor cannot tell whether 11.2 is low.
2. No flag on abnormal values, so a critical result is missed in a long report.
3. Missing collection time. For glucose, fasting and post-meal samples are meaningless without it.
4. Wrong sex or age on the request, which picks the wrong reference range.
5. Report signed by the technician only.
6. Several visits, several loose papers. A combined report of the patient's tests over time is easier for the doctor to read.

How OPDly prints the report for you

In OPDly's lab software, each test has its own unit and reference range — by gender and age where needed — and values outside the range are flagged High or Low as you type. Every sample gets a sample ID and barcode label. The report prints on your own letterhead or a generated header, repeats the patient block on every page with the collected, received and reported times, and ends with up to four signatories, each with qualification, registration number and an optional scanned signature. Results can go for verification before release, and the patient gets a secure link to the report on WhatsApp. Tests from different days can be printed as one combined report.

Frequently asked questions

What is the reference range on a lab report?

It is the range of values found in healthy people for that test, as validated by the lab for its method and analyser. Values outside it are flagged High or Low. Ranges can differ between labs, so always read a result against the range printed on the same report.

Who can sign a pathology report in India?

A registered medical practitioner with a postgraduate qualification in pathology, as upheld by the Supreme Court in 2017. Microbiology and biochemistry reports may be signed by specialists in those subjects, as clarified in 2019.

Should a lab report show the sample collection time?

Yes. The collected, received and reported times show the sample was handled correctly, and some results — fasting glucose, for example — only make sense with the collection time.

Can a lab report be sent on WhatsApp?

Yes. Many labs share a link or PDF on WhatsApp. A link that opens the report online is safer than forwarding a file, because the report stays tied to your lab and can't be edited.

What size should a lab report be?

A4 is standard, because reports often run to several pages and are filed with the patient's records.
