Cell distribution
| Cell type | 5th percentile |
Median | Mean | 95th percentile |
|---|---|---|---|---|
| CD34+ cells | 0.7 | 1.8 | 1.8 | 2.8 |
| Hematogones/Immature cells | 2.5 | 5.9 | 5.9 | 9.2 |
| Lymphocytes | 5.7 | 13.4 | 14.2 | 25 |
| Granulocytes | 59.5 | 73.7 | 73.4 | 85.5 |
| Monocytes | 2 | 3.5 | 3.7 | 5.8 |
| Remaining cells | 1.4 | 2.5 | 2.8 | 4.5 |
Viability
Viability of the cells in flow cytometry should be around 95% but not less than 90%.[2]
CD4/CD8 ratio
A ratio of 1.5 and 2.5 is generally considered normal.[3][notes 1]
Kappa/lambda ratio
Normal range: 1.35 - 2.95.[4]
Notes
- ↑ Normal CD4/CD8 ratio is affected by multiple factors, including sex, age, ethnicity and genetics
