Pregnancy Test: When and How to Use It Correctly
Home pregnancy tests detect the hormone hCG in your urine. Used correctly and at the right time, they are highly accurate — here is how to get a reliable result.
When to take the test
For the most accurate result, test from the first day of your missed period. If you test earlier, hCG may be too low to detect. Some sensitive tests claim results a few days early, but early negatives should always be repeated after your period is late.
How to use it correctly
- Use first-morning urine, when hCG is most concentrated.
- Read the instructions — dip time and wait time vary by brand.
- Wait the full recommended time (usually 3–5 minutes) before reading.
- Read within the stated window; lines that appear much later can be misleading (evaporation lines).
Reading your result
Two lines (or a "pregnant" reading) means hCG was detected. Even a faint line usually means positive. One line means no hCG was detected — but if your period still does not come, retest in a few days or see your doctor.
False positives and negatives
False negatives are more common than false positives and usually happen from testing too early or using diluted urine. False positives are rare but can occur with certain medications or medical conditions. A blood test at a clinic can confirm and even estimate how far along you are.
Frequently asked questions
Can I take a test at night?
Yes, but first-morning urine is more concentrated and reliable, especially very early on.
Does a faint line count?
Usually yes — any visible line within the read time typically indicates a positive. Retest in a couple of days to see it darken.
Should I confirm with a doctor?
A positive home test should be followed by a visit to confirm the pregnancy and begin antenatal care.
