INDEX / The real OPD problem
You've checked the range — but what now? Repeat, treat, or refer today? Textbooks give theory, protocols are too long. This set fills the gap in between.
Which value do I look at first?
Critical, treatment-changing or just mildly abnormal — they all look the same at first glance.
Is the report even right?
Haemolysis, wrong tube, fasting errors — half of all wrong results are created at sample collection.
When should I refer?
You need a number-based trigger, not a guess.
Lab Report Decoded gives you ⬆ HIGH / ⬇ LOW causes for every test, a ⚠ 10-minute action plan for critical values, and every case ends with “What to do now” + “When to refer”.
Patient: R. Sharma · 54 / M · Ref: OPD

INDEX / What readers say

★★★★★
“Both volumes look like useful additions to my medical reference collection. Volume 1 focuses on understanding individual tests, while Volume 2 covers case-based interpretation. The practical format makes the set worth considering for regular study.”
Dr. Rohan Kulkarni
Sample review · Doctor

★★★★★
“I was looking for a structured guide to laboratory investigations rather than scattered notes. The two-volume concept, with test references in one book and clinical cases in the other, seems practical for revision and learning.”

INDEX / FAQ
Volume 1 is the “dictionary” — range, high/low causes, sample and critical value for every test. Volume 2 is the “decision manual” — 60+ cases that teach you to read the full report, recognise the pattern, choose the next test and know when to refer. They work best together.
Yes. The set is built for GPs, BAMS & BHMS practitioners, interns and rural medical officers — it teaches you to read modern lab reports step by step.
No. All lab reports and cases are synthetic — names, labs and report numbers are invented. The values are kept medically plausible so you can practise on them.
No. It is an educational quick-reference and decision-support book. Reference ranges vary by lab, and dose/treatment decisions rest with the treating doctor.
It is aligned with current versions of ICMR, WHO, ADA, KDIGO, ATA, the Surviving Sepsis Campaign, IAP paediatric references, NABL/CLSI and Indian national programmes (NTEP, NACO, NVHCP, NCVBDC).
