What is haematocrit?
The proportion of blood volume made up of red blood cells.
BiomarkerHQ groups haematocrit under Blood count. On lab reports it can also appear as hematocrit, hct, pcv and packed cell volume.
Haematocrit units and conversion
BiomarkerHQ stores each haematocrit result in the unit printed on the report, and charts and compares results in %.
1 L/L = 100 %
1 % = 0.01 L/L
| L/L | % |
|---|---|
| 0.3 L/L | 30 % |
| 0.35 L/L | 35 % |
| 0.4 L/L | 40 % |
| 0.45 L/L | 45 % |
| 0.5 L/L | 50 % |
| 0.55 L/L | 55 % |
| 0.6 L/L | 60 % |
| % | L/L |
|---|---|
| 30 % | 0.3 L/L |
| 35 % | 0.35 L/L |
| 40 % | 0.4 L/L |
| 45 % | 0.45 L/L |
| 50 % | 0.5 L/L |
| 55 % | 0.55 L/L |
| 60 % | 0.6 L/L |
For another value, use the lab unit converter. It converts units only and does not interpret a result.
Tracking haematocrit over time
In BiomarkerHQ, each haematocrit result is saved with its collection date, its unit and the reference range printed on that report. The timeline charts the results across your draws against the range from each of your own reports, and any two draws can be compared side by side.
- Keep the unit printed on each report. Convert only to compare.
- Keep each report's own range with its result. See why ranges differ between labs.
- Compare the same lab and conditions where you can. See how to compare two blood tests.
