Instant-view® Lateral Flow Test
Lateral flow assays have provided a very useful tool for three decades. Use of the technology is widespread and has proven an inexpensive way to screen, qualitatively and semi-quantitatively, in point-of-care environments. Lateral flow tests are used for medical diagnostics and detect the presence or absence of a target analyte in a sample matrix without the need for additional specialized and expensive medical equipment. The tests are utilized either for at-home-testing, point-of-care testing, or in clinical laboratories, depending on the tests regulatory clearances.
Throughout over 20-year history, ALFA has fine-tuned our manufacturing capabilities to a level that ensures the highest quality of lateral flow test output. All products are produced in the USA. ALFA's Instant-view® lateral flow tests stand for quality our customers have come to rely on and trust.

How do ALFA's Instant-view® tests detect pregnancy?
ALFA's pregnancy tests detect Human chorionic gonadotropin (hCG). hCG is a hormone that is released by the placenta, which helps the fetus develop. Since the placenta only forms after a woman becomes pregnant, hCG is a reliable marker that indicates pregnancy. Within nine days after a sperm fertilizes an egg in the woman’s fallopian tube, the embryo travels to the uterus, where it implants itself into the uterine wall. After implantation, the embryo grows a placenta, which serves as the conduit between the fetus and the mother’s blood stream. hCG levels rise very rapidly and peak at around 14 weeks after a woman’s last menstrual cycle. hCG is can be detected in a woman’s blood as soon as 6 days after implantation, before she misses her next period.
hCG is released by the placenta into the mother’s bloodstream, but some of it also escapes filtration in the kidneys and enters the urine. Thus, pregnancy urine tests often detect the presence of hCG. ALFA’s instant pregnancy testing kits are 99% accurate. Our kits work with either urine alone, or both urine and serum. Our Instant-View technology is sensitive enough to detect 25 mIU/mL of hCG.
Though the presence of hCG in the blood is widely regarded as a sign of pregnancy, there are other conditions in which a woman produces hCG. For example, a tumor or abnormal growth inside a woman’s ovaries or uterus may release hCG. In men, tumors in the testicles also produce hCG.
