The control includes AFP, Free Estriol, hCG and Inhibin A
, making it ideal for laboratories performing triple or quadruple marker screening.

Activin-A is a dimeric glycoprotein composed of two B subunits of inhibin A
Of four markers studied, inhibin A
was the only one associated with the risk of stillbirth after adjustment for the other markers and risk factors known before pregnancy But elevated levels of this marker alone had a positive likelihood ratio of just 5.
Serum inhibin A
and inhibin B in healthy prepubertal, pubertal, and adolescent girls and adult women: relation to age, stage of puberty, menstrual cycle, follicle-stimulating hormone, luteinizing hormone, and estradiol levels.
Seventy-nine matched case-control sets of maternal serum samples (each Down syndrome case matched to 5 controls) from 11 through 13 completed weeks of gestation were taken and assayed for levels of free beta-hCG, total hCG, and inhibin A
In cases of Down syndrome, inhibin A
concentration is, on average, approximately twice as high as in unaffected singleton pregnancies (1).
Dimeric inhibin A
, a fourth biochemical marker for second-trimester Down syndrome screening, became more widely available last month when a national commercial laboratory added the test to its traditional triple-marker screening test.
The ACTIVE Inhibin A
ELISA for in vitro diagnostic use is available as an aid in the diagnosis and monitoring of various hormonal reproductive disorders.
