Platelet Count
What it measures
Reported per cubic millimetre (cells/cumm, identical to /µL) on Indian reports and as 10⁹/L internationally, a thousand-fold difference in the printed number for the same count. Some Indian labs also report in lakhs per cumm, where 2.5 lakh/cumm is 250,000/cumm. Platelet counts are also the value most often affected by how the sample was handled, so an unexpected result is commonly rechecked before it is acted on.
Reading it in a different unit
This lab reports Platelet Count in /ul. Reports from other labs — especially ones using European or US-style formatting — sometimes use a different unit for the same measurement. The relationship between them:
/cumm, cells/cumm are the same value as /ul under a different name — nothing to calculate, just a different label on the same number.
| Reported unit | How it relates to /ul |
|---|---|
| 10*9/l | /ul = 10*9/l × 1000 |
| 10^9/l | /ul = 10^9/l × 1000 |
| k/ul | /ul = k/ul × 1000 |
| lakh/cumm | /ul = lakh/cumm × 100000 |
| thou/ul | /ul = thou/ul × 1000 |
Unit conversions verified against published molar masses and LOINC definitions. This is not a diagnostic reference — the normal range for any test is set by the laboratory that ran it and printed on your report.
Why this matters for tracking a trend
A value plotted next to earlier results only tells you something if every point is on the same scale. Two readings of the same test from two different labs, in two different units, can look like a dramatic change when nothing about your actual result changed — only the unit did. Converting to one scale before comparing is what keeps a trend line honest.
LOINC codes for this test: 26515-7, 777-3.
