What is the principle behind this test for hCG?

Principle of the test: The Visual hCG ELISA Test is a sandwich enzyme immunoassay (8-9) for the determination of human chorionic gonadotropin in urine or serum. The method employs two monoclonal antibodies to selectively identify hCG in urine/serum with a high degree of sensitivity.

What does hCG control positive mean?

A positive hCG means that a woman is likely pregnant. However, false-positive tests can occur if a woman is post-menopausal or taking hormone supplements. The blood level of hcG in a woman with an ectopic pregnancy usually rises at a slower rate than normal.

The Consult Diagnostics hCG Combo Test is a rapid chromatographic immunoassay for the qualitative detection of human chorionic gonadotropin (hCG) in urine or serum to aid in the early detection of pregnancy.

What is the meaning of C and T in pregnancy test?

The test window shows two lines—one for the control line (C) to make sure the test worked and another, the test line (T), that shows a positive result. Positive: If two lines show up, even if the test line (T) is very faint, that’s a positive—or pregnant result.

The Alere™ hCG Combo Cassette (20/10 mIU/mL) is a test used for the detection of human chorionic gonadotropin (hCG), a hormone produced during pregnancy. A simple procedure provides easy-to-read results in 3 minutes for urine or 5 minutes for serum.

How does the hCG card pregnancy test work?

The hCG Card Pregnancy Test is a rapid chromatographic immunoassay for the qualitative detection of human chorionic gonadotropin in urine to aid in the early detection of pregnancy. SUMMARY Human chorionic gonadotropin is a glycoprotein hormone produced by the developing placenta shortly after fertilization.

What is the principle of a urine pregnancy test?

Principle of Urine Pregnancy Test. Most of them qualitatively detect the presence of hCG in urine specimen at the sensitivity of 25 mIU/mL. The test uses two lines to indicate results. The test line utilizes a combination of antibodies including a monoclonal hCG antibody to selectively detect elevated levels of hCG.

How many urine specimens should be used to test for hCG?

FDA recommends that at least 100 fresh, human urine specimens be used. Each specimen should be split between the subject and the professional, who should perform testing on the predicate device (for professional use or OTC use) and the new device.

When to use OneStep hCG urine rapid test?

Intended Use OneStep HCG Urine Rapid Test is a test kit for the determination of hCG (Human Chorionic Gonadotropin) in urine specimens. There is an appearance of hCG in urine soon after conception, and its subsequent rapid rise in concentration during early gestational growth.
