Abstract
The invention relates to a method of determining the concentration of luteinizing hormone (hereinafter referred to as 'LH') in the body fluid of a woman and thereby determining the day when said woman ovulates, as well as to compositions for effecting this determination. The composition comprises human chorionic gonadotropin (hereinafter referred to as 'HCG') coupled to red blood cells by means of glutaraldehyde as coupling agent therebetween, which composition in carrying out the test is mixed with the body fluid of the woman and an anti-HCG serum in an amount adjusted to react with approximately 50 international units (I.U.) of HCG per liter of the body fluid, generally urine, so that agglutination occurs when LH equivalent to less than 50 I.U. of HCG/L is present and no agglutination when at least 50 I.U. HCG/L is present. The day of highest concentration of LG equivalent to HCG indicating the day of ovulation.
