[Measurement of LH in urine by HI-gonavis test for the predetermination of ovulation (author's transl)]. 1978

H Brandau

The immunological LH/HCG test HI-Gonavis was used to measure the LH-excretion in urine of 30 patients during 1 to 3 cycles. The level of LH in plasma was determined simultaneously by radioimmunoassay. 12,5IU LH/L urine, the limit of sensitivity of HI-Gonavis, coincide with 7,2 mIU/ml plasma. 50 or 100 IU LH/L urine were found in patients showing a LH plasma level which was higher than 12,5 mIU/ml. In the ovulatory cycle this value is reached 1 day before the LH-peak. From the correlation of the preovulatory increase of LH in the plasma and the LH-excretion in the urine it can be concluded, that the detection of 50 IU LH/L urine indicates the ovulation within the next 12--30 hours. The practicability of this test for the predetermination of ovulation is demonstrated by examples.

D007986 Luteinizing Hormone A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Luteinizing hormone regulates steroid production by the interstitial cells of the TESTIS and the OVARY. The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.

D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.
