HCG (quantitative)
Alternative names:
beta-HCG - quantitative; human chorionic gonadotrophin - quantitative; quantitative serum beta-HCG; repeat quantitative beta HCG; serial beta HCG
What the risks are:
- excessive bleeding
- fainting or feeling lightheaded
- hematoma (blood accumulating under the skin)
- infection (a slight risk any time the skin is broken)
- multiple punctures to locate veins
Special considerations:
Drugs that can decrease HCG measurements include diuretics and promethazine.
Drugs that can increase HCG measurements include anticonvulsants, antiparkinsonian drugs, phenothiazine, and promethazine.
Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.
