viability
is the earliest biochemical marker for pregnancy, detected as early as 7-10 days after conception.
HcG
higher than normal levels of Hcg can indicate?
abnormal gestation Ex. Down Syndrome
pregnancy test for the beta subunit of Hcg in serum or urine sample use radioactive labeled marker in the lab. These test accurate with Low Hcg and can detect before the first menstrual period.
Radioimmunoassay (RIA)
is a serum test that measures the ability of a blood sample to inhibit the binding of radiolabeled hcg receptors. 90-95% accurate from 6 to 8 days after conception.
Radioreceptor assay (RRA)
this testing is the most popular method of testing for pregnancy. It uses a specific monoclonal antibody (anti-hcg) with enzymes to bond with hcg in urine.
ELISA
Those changes noticed by the woman (amenorrhea, fatigue, nausea, vomiting, breast changes)
presumptive signs
Those changes observed by the examiner ( Hegar sign, ballottement, pregnancy test, goddell sign, chadwick sign, braxton hicks contractions)
