Description
Earliest test can be performed:
Depends on cycle length.
Sensitivity:
Over 99% accurate. The test should not detect an LH surge at concentrations less that 22mIU/ml, and should detect an LH surge at concentrations over 40mIU/ml. (LH is secreted throughout the menstrual cycle in varying quantities. All women have a base level of LH in their urine, and this is generally in the range between 6-13mIU/ml. A surge of LH increases this level to the range 50-200mIU/ml).
Stream or dip urine test.
Counselling Points:
