Table 5 Relations between serum progesterone cut off levels and viability of the pregnancy
From: Relation between single serum progesterone assay and viability of the first trimester pregnancy
Variables | Viable | Non-viable |
|---|---|---|
Pregnancy group (Total number = 178) | Pregnancy group (Total number = 82) | |
Serum Progesterone at cut off level 10 ng/ml | ||
Number of cases with serum progesterone < 10 ng/ml (%) | 12 (6.7%) | 65 (79.3% = sensitivity) |
Number of cases with serum progesterone > 10 ng/ml (%) | 166 (93.3% = specificity) | 17 (20.7%) |
Serum Progesterone at cut off level 20 ng/ml | ||
Number of cases with serum progesterone < 20 ng/ml (%) | 2 (1.1%) | 78 (95.1% = sensitivity) |
Number of cases with serum progesterone > 20 ng/ml (%) | 176 (98.9% = specificity) | 4 (4.8%) |
