Urine For HCG (Pregnancy Test)
- Sample Type
- Urine
- Fasting
- No
- Unit
- mIU/mL
Function
The Urine hCG test detects the presence of Human Chorionic Gonadotropin, a hormone produced by the placenta shortly after an embryo attaches to the uterine lining. This hormone rises rapidly in early pregnancy, doubling approximately every 48 to 72 hours. While blood tests are more sensitive, urine tests provide a rapid, non-invasive method for initial pregnancy screening.
Why it is Ordered
This test is primarily ordered to confirm pregnancy in individuals with a missed menstrual period. It is also used in emergency rooms and before surgical procedures or certain medical imaging (like X-rays or CT scans) to ensure that a patient is not pregnant, as treatments could potentially harm a developing fetus.
Associated Conditions
- Normal Intrauterine Pregnancy: The most common cause of a positive result.
- Ectopic Pregnancy: Pregnancy occurring outside the uterus; hCG levels may rise more slowly than normal.
- Molar Pregnancy (Gestational Trophoblastic Disease): Abnormal tissue growth in the uterus that produces very high levels of hCG.
- Germ Cell Tumors: Rarely, certain cancers of the ovaries or testes can produce hCG.

Why Context Matters
The primary confounding factor is urine concentration. Testing too early in the morning with dilute urine (after drinking a lot of water) can lead to a false negative. Conversely, certain medications containing hCG (used in fertility treatments) or blood/protein in the urine can lead to false positives. Biotin supplements (Vitamin B7) are also known to occasionally interfere with immunoassay results.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
