How to Use a Home Pregnancy Test Correctly: The Complete First Step Guide

Few moments feel as important as waiting for a pregnancy test result. A home test is accurate when it is used correctly — and most "wrong" results come from testing too early or reading the result at the wrong time. This guide walks you through every step with the First Step Pregnancy Test Pen and First Step Pregnancy Test Cassette.

How a home pregnancy test works

After a fertilised egg implants in the uterus, the body starts producing a hormone called hCG (human chorionic gonadotropin). Its level roughly doubles every two to three days in early pregnancy. A home test detects hCG in urine and shows a second line when the hormone is present.

When is the best time to test?

  • From the first day of your missed period — this is when most tests give the most reliable result.
  • First-morning urine is the most concentrated, which matters if you are testing early.
  • If the result is negative but your period still hasn't arrived, repeat the test after 2–3 days.

Pen or cassette: which one should I choose?

The pen (midstream) is held directly in the urine stream for a few seconds — quick and easy. The cassette uses a dropper: you collect urine in a clean cup and add a few drops to the sample well, which gives you more control over the amount. Both detect hCG the same way; choose whichever feels easier for you.

Step by step

  1. Check the expiry date and that the foil pouch is sealed.
  2. Bring the test to room temperature and open it just before use.
  3. Pen: hold the absorbent tip in the urine stream for the time shown on the leaflet. Cassette: add the stated number of drops to the sample well.
  4. Lay the test flat and wait for the time stated on the pack (usually a few minutes).
  5. Read the result within the reading window — not hours later.

How to read the result

  • Two lines (control + test): positive — even if the test line is faint.
  • One line (control only): negative.
  • No control line: the test is invalid; repeat with a new test.

A line that appears after the reading window has passed (an "evaporation line") should not be counted.

Why results can be misleading

  • Testing too early, before hCG is high enough.
  • Drinking a lot of fluids before testing, which dilutes urine.
  • Reading the result too late.
  • Some fertility medicines containing hCG can cause a positive result.

What to do next

A positive result should always be confirmed by a doctor, who may request a blood test or ultrasound. Book an appointment early to start prenatal care and folic acid if you haven't already. Seek urgent care if you have severe abdominal pain, heavy bleeding or dizziness.

Frequently asked questions

Is a faint line a positive result?

Yes. Any visible test line within the reading time usually means hCG has been detected. Repeat in 48 hours — the line typically gets darker as hCG rises.

Can I test in the evening?

Yes, from the day of your missed period. If you are testing earlier, first-morning urine gives the best chance of detection.
