Why This Test Is Done

Your healthcare provider may order this test if you have symptoms of pregnancy (such as missed periods, nausea, or breast tenderness) or if you’re at risk for early pregnancy loss. It can also be used to monitor β-hCG levels in cases of suspected ectopic pregnancy or unexplained bleeding.

How the Test Works

A 24-hour urine sample is collected to capture β-hCG levels throughout the day. The hormone is naturally produced after implantation, so detecting it in urine helps confirm pregnancy or rule it out.

Sample Collection

You’ll need to collect all urine for a full 24-hour period in a clean container. Empty your bladder before starting and discard the first urine. Collect all urine afterward, then discard the last sample before bedtime. Label the container with your name and date.

What to Expect

The test is simple but requires consistency—missing any urine can affect accuracy. Follow your provider’s instructions carefully to ensure reliable results.

Clinical interpretation

Frequently asked questions

A consistently low or absent β-hCG level in early pregnancy may indicate a miscarriage or ectopic pregnancy. High levels could suggest a viable pregnancy, but further evaluation may be needed for confirmation.
This test is qualitative, meaning it only tells you if β-hCG is present (positive) or not (negative). It does not provide exact amounts, so it’s not used for monitoring changes over time.
If you have irregular menstrual cycles or recent hormonal treatments, your results may be less reliable. Always discuss your medical history with your provider before testing.
Urine β-hCG tests are typically done in early pregnancy (usually 4–9 weeks). If you’re unsure about timing, ask your provider for guidance.
False positives or negatives can occur, especially with certain medications or medical conditions. Your provider will interpret results in the context of your symptoms and medical history.
No special preparation is needed, but avoid excessive fluid intake right before testing to ensure accurate collection. If you’re pregnant, this test is not the same as a blood β-hCG test, which provides more detailed results.
