pregnancy-associated plasma protein A

PAPP-A is considered to be a trophoblast production, and electrophoretic analysis is located in the serum protein α2 globulin region. Immune diffusion method: serum maternal <320mg / L, pregnancy serum concentration gradually increased, the average value of about 40mg / L at the 40th week, decreased rapidly after delivery, can not be measured in 3 to 5 weeks, the level of amniotic fluid and The mother blood is parallel. Basic Information Specialist classification: maternity check check classification: biochemical examination Applicable gender: whether women are fasting: fasting Analysis results: Below normal: normal. Normal value: Pregnancy-associated plasma protein A (immune diffuse serum mother): 0-320mg/L Above normal: Found in twin pregnancy, pregnancy-induced hypertension, pregnant women with diabetes, eclampsia, various malignant tumors, oral contraceptives. negative: Positive: Tips: The radioimmunoassay method has high sensitivity and can be measured in the early pregnancy. It gradually increases from 7 weeks to 40 weeks, and disappears 2 to 3 days after delivery. Normal value The serum of maternal body <320mg/L, the serum concentration of pregnancy is gradually increased, the average value is about 200mg/L at the 40th week, and it decreases rapidly after delivery. It can not be measured in 3~5 weeks, the level of amniotic fluid and the mother Blood parallel. Clinical significance Serum levels higher than the corresponding normal pregnant women are seen in twin pregnancy, pregnancy-induced hypertension, pregnant women with diabetes, eclampsia, various malignant tumors, oral contraceptives. High results may be diseases: preeclampsia considerations The radioimmunoassay method has high sensitivity and can be measured in the early stage of pregnancy. It gradually increases from 7 weeks to 40 weeks, and disappears 2 to 3 days after delivery. Inspection process Immune diffusion method. Not suitable for the crowd no. Adverse reactions and risks no.
