that promotes villous edema
b. Development of a zygote that contains
only maternal chromosomes
c. Increased placental androgen production
the leads to maternal virilization

Q

Increased serum free thyroxine levels in women with hydatidiform moles stem from increases in which of the following:

A. Maternal estrogen levels
B. Fetal thyroxine production
C. Maternal progesterone levels
D. Maternal B-HCG levels

A

D. Maternal B-HCG levels

thyrotropin-like effects of hCG frequently cause serum free thyroxine (fT4) level to be levated and TSH levels to be decreased

Q

What is the phenomenon called when high serum hCG levels cause a false negative? Why?

A

Hook effect; excessive hCG level oversaturate the assay’s targeting antibody and create a falsely low reading
