What To Think About
Blood estrogen levels are a more accurate indicator of how well the ovaries are working than urinary estrogen levels.
Tests that measure blood levels of
progesterone, luteinizing hormone, and follicle-stimulating hormone are often used to study the problems that can affect fertility and the menstrual cycle. In some cases a combination of screening tests is done in the
first trimester to look for Down syndrome. The first trimester screening often combines ultrasound measurement of the thickness of the fetus's neck (nuchal translucency) and measurements of hCG and a protein called pregnancy-associated plasma protein A to check for problems. To learn more, see the topic Birth Defects Testing. The level of estriol in the blood is often used in a maternal serum triple or quadruple screening test. To learn more, see the topic
Triple or Quad Screening for Birth Defects.
