From: New discoveries on the biology and detection of human chorionic gonadotropin
Number of valid non-gestational menstrual cycles | 371 cycles |
|---|---|
Timing of LH peak concentration during valid menstrual cycles mean ± SD) | 14.6 ± 3.1 days |
Number of urines tests | 11,122 |
Length of menstrual cycle, start of bleeding to next start of bleeding | 28.6 ± 3.8 days |
Of valid cycles, the mean peak LH concentration ± SD | 210 ± 161 mIU/ml |
Number of positive daily hCG tests, 1 IU/L sensitivity, in valid menstrual cycles | 371 |
Proportion of menstrual cycles with positive regular hCG test, 1 IU/L sensitivity | 332 (89%) cycles |
Cycles with positive regular hCG test, regular hCG mean ± SD | 1.52 ± 0.91 mIU/ml |
Cycles with positive hCG test, hCG range | 1.0 – 9.3 mIU/ml |
