The pregnancy tests are used to obtain quick visual, qualitative results for early detection of pregnancy hCG (human Chorionic Gonadotropin) hormone in urine samples. Human Chorionic Gonadotropin (hCG) is a glycoprotein hormone secreted by the developing placenta shortly after egg fertilization. hCG can be detected in the urine (also blood and serum) of a patient as early as 6 to 15 days after conception. The intended use of these tests is to screen for early beta hCG development which occurs between 5-50 mIU/mL. The hCG is released by the pituitary gland and and peaks at 100,000-200,000 mIU/mL the end of the first trimester.

The ovulation tests are used to obtain quick visual, semi-quantitative results for early detection of Luteinizing Hormone (LH) in urine samples. The LH surge is used to predict a release of mature ovum within 24-48 hours, at which the patient is most likely to become pregnant. Luteinizing Hormone (LH) plays important roles in the regulating the ovulation and ovarian functions during the menstrual cycle. Normally present in very small concentration in urine, LH rapidly increases in the mid cycle (commonly referred to as "ovulation surge"), usually 1 to 2 days prior to release of the mature ovum (ovulation). By monitoring the surge of LH in urine it is possible to determine the optimal chance for egg fertilization and planned pregnancy.
