The Biomerica LH test is a one-step test for detection of Luteinizing Hormone (LH) in urine and is intended for the qualitative determination of ovulation surge, the most likely time for conception to occur. The test will detect the presence of LH at a sensitivity of 30 mIU/ml. The user simply places four drops of urine into the device and reads the result. A positive result is indicated by observing the intensity of color between two unmistakable rose-pink color bands, which appear in as little as one minute. This version is available in bulk OEM and is intended for in vitro diagnostic use.
