What’s inside this reference library
Whether you’re holding a blood test report, a set of vitals from a health checkup, or the results of an imaging scan, the hard part is rarely getting the number — it’s knowing what it means. Each guide here takes one measurement, explains its normal range for Indian adults, and walks through what a high or low result can point to.
Blood & lab tests
From a complete blood count (CBC) — your red blood cell, haemoglobin and white cell numbers — to the lipid profile, HbA1c, thyroid, and kidney and liver function tests. Each guide covers the normal range and what different blood test results mean.
Vitals & wearables
Blood pressure, resting heart rate, blood oxygen (SpO₂), heart rate variability and VO₂ max — the everyday health checks you get in a clinic or from a smartwatch — with the normal ranges and what a reading outside them can signal.
