Fertility and Hormone Testing


OVULATION-LH - for the detection of human Luteinizing Hormone (LH) in urine, is available in card and midstream formats. As more and more couples are planning their pregnancies, the ability to predict a woman's most fertile days is fast becoming an important factor in this planning. Ovulation is a natural process occurring once a month during a woman's fertile years. As this process occurs during only two days each month, accurate and reliable detection is important.

MENOPAUSE - FSH- available in card and midstream formats, detects human Follicle Stimulating Hormone (FSH) in urine. Measurement of FSH is useful for the detection of menopause because when this condition exists FSH levels are elevated. This test is designed as a preliminary test to determine if a woman is entering menopause or not, as many of the symptoms such as hot flashes and insomnia occur years before the menstruation ceases. Untreated menopause has been linked to several ailments i.e. loss in bone density, increase in heart disease as the result of changes in blood vessels, and emotional ill health.

TSH - a screening test in serum for human Thyroid Stimulating Hormone (TSH) detection. When circulating thyroid hormone levels fall below normal, the pituary gland secretes TSH. This acts on the thyroid gland to produce more thyroid hormones. When circulating thyroid hormone levels rise above normal, the pituary releases less TSH, causing the thyroid to produce and secrete less thyroid hormones. Testing basal serum concentration of TSH is essential in the investigation of suspected hypothyroidism (abnormally low levels of thyroid hormones). A raised concentration of TSH confirms a primary cause of the disease, while a normal or low concentration excludes it or, more rarely, indicates a pituary or hypothalmic cause.

PROLACTIN - for the detection of human Prolactin (hPRL) in serum. Human Prolactin, secreted by anterior pituitary gland, is essential for breast development and lactation in women. Elevated levels can be detected after the eighth week of pregnancy and continue until giving birth. After birth, prolactin levels return to normal within three weeks in the absence of breastfeeding. Normal females show prolactin levels only slightly higher than males. Abnormally high levels of PRL are associated with infertility in men and women, male impotence, and primary hypothyroidism.
