Qualitative HCG
HCG is a hormone, produced by
placental tissue.
- Shortly after implantation of a fertilized ovum in the uterine
lining, HCG begins to be produced.
- Levels of HCG approximately double every 2-3 days in a normal
pregnancy.
- By the time of the first missed menstrual period, pregnancy tests
are usually positive (with a sensitivity of 30-35 mIU/ml).
Urine is normally used for the test. A morning urine is more sensitive
(in borderline situations) because it is more concentrated.
Serum can be used, and is equally reliable.
Elevations caused by:
- Pregnancy
- Gestational Trophoblastic Disease
Decreases caused by:
- Miscarriage (spontaneous or induced)
- Following obstetrical delivery
- With resolution of an ectopic pregnancy
