Maternal serum PAPP‐A and free β‐hCG at 12, 22 and 32 ... - OBGYN
Multiples of the normal median (MoM) of free βHCG is a valuable parameter in evaluation of risk of adverse pregnancy outcomes. In the current retrospective study, we assessed the maternal and...
Beta hCG Levels in Pregnancy: Week by Week - Verywell Family
The detection of the free-beta subunit hCG is suggestive of malign cancer and poor prognosis. [7] hCG synthesized by the anterior pituitary gland is produced at low levels throughout the menstrual cycle and mimics the effects of the luteinizing hormone (LH). [4] Go to: Development.
hCG Levels: How to Interpret Pregnancy Blood Test Results - MD.Saúde
hCG is a hormone that plays an important role in pregnancy, and levels can vary widely at this time and between individuals. Outside pregnancy, a high hCG level may be a sign of a health...

Down's syndrome screening methods. The evidence base for the screening tests. Down's syndrome screening in multiple pregnancy. The future of Down's syndrome screening. It is important to emphasise that the decision to have any form of screening should be an informed one.
Extreme βHCG levels in first trimester screening are risk ... - Nature
A high serum free β-hCG level (>2.25 MOM) was associated with a higher rate of intrauterine growth restriction (5.7% vs 0.7%, P < .001) and a trend towards a higher rate of preterm premature rupture of membranes (5.7% vs 2.5%, P = .09) compared to free β-hCG values <95th percentile. Conclusion.
hCG levels: Ranges, what they mean, and when to seek help
In addition to secreting intact hCG, tumors may produce disproportionate quantities of free alpha subunits or, more commonly, free beta subunits. Assays that detect both intact hCG and...
The use of free beta-hCG in antenatal screening for Down's syndrome
The Free Beta hCG Test means that you are being tested for determining the amount of the Free Beta-hCG hormone present in the body. hCG or Human Chorionic Gonadotropin is a hormone that is made by the placenta in women during their pregnancy period.
Human Chorionic Gonadotropin - StatPearls - NCBI Bookshelf
Free Beta HCG (Human Chorionic Gonadotropin) is produced by the placenta during pregnancy. This test is used to confirm pregnancy, detecting ectopic pregnancy, potential miscarriage and screening of downs syndrome. High levels of beta HCG may also indicate a specific type of ovarian cancer in women and testicular cancer in men.

First trimester biochemical screening for Down syndrome: free beta hCG ...
This screening is done by a combination of two biochemical markers i.e. serum free β-human chorionic gonadotrophin (free β-hCG) and pregnancy associated plasma protein A (PAPP-A), maternal age and fetal nuchal translucency (NT) thickness at 11 + 0-13 + 6 weeks of gestation.
