IB10 sphingotest® beta-hCG

IB10 sphingotest® beta-hCG is a rapid point-of-care (POC) immunoassay for the quantitative in vitro determination of human chorionic gonadotropin (hCG) in human lithium-Heparin whole blood and plasma. The assay detects total hCG, measuring both the intact hCG molecule and its free beta subunit. The quantitative measurement of hCG aids in the early detection of pregnancy.

The test is designed for professional use only and may be used on sites where near patient testing is practiced.

Cat. No. IVR-IB54 | beta-hCG (package of 10 discs)

Clinical Significance

hCG is the primary analyte used for pregnancy confirmation and monitoring due to its rapid rise in both blood and urine soon after conception (1). The detection of hCG within 3 - 4 weeks of the last menstrual period is the most reliable indicator for the confirmation of pregnancy. During a normal pregnancy, levels of hCG in the blood vary but are approximately 25 - 50 mIU/mL in the week after conception and rise exponentially doubling every 1.5 - 3 days during the first six weeks (2,3). hCG levels continue to rise through the end of the first trimester, followed by a slow decline as the pregnancy reaches full-term (~ 40 weeks).

Expected Values

Each laboratory should establish its own expected values that represents the population that is to be evaluated at their facility. As a guide, the following ranges were determined. The IB10 sphingotest® beta-hCG Test was used to determine the concentration upper reference limit of hCG in human plasma samples collected from apparently healthy, non-pregnant individuals. The 95th percentile upper reference limit as determined with the samples is 5.42 mIU/mL hCG.
