Effect of the lymphocyte count in peripheral blood on the correlation between the TaqMan and cPCR assays
| Sample type and unit of measurement | Spearman r2 for group-categorized cross-tabulation between TaqMan and cPCR assays by lymphocyte count:
|
|
|---|---|---|
| <2 × 109 PBLs/liter (n = 17 pairs) | ≥2 × 109 PBLs/liter (n = 27 pairs) | |
| Whole blood | ||
| Copies/ml | 0.953 | 0.918 |
| Copies/μg of DNA | 0.913 | 0.918 |
| Copies/105 PBLs | 0.899 | 0.937 |
| Plasma (copies/ml) | 0.355a | 0.706 |
