Home pregnancy tests: are they accurate?

If you are sexually active and have missed your period, pregnancy is one possible reason. A home pregnancy test may be the next logical step. Below are answers to some of women’s most common questions about at home tests.

How does a home pregnancy tests work?

Around 10 days after conception (when a sperm fertilizes the egg), the embryo implants into a woman’s uterus. Beginning at that time, the woman’s body begins to release a hormone called hCG (human chorionic gonadotropin) to maintain the pregnancy. This hormone is exclusive to pregnancy.  An at home pregnancy test detects this hormone in urine.

When is the best time to take a urine pregnancy test?

The hCG level in early pregnancy doubles about every 2-3 days. Because of this, the best time to take a urine pregnancy test is a couple days after you miss your period with your first morning urine (when hCG is the highest).

Timing of ovulation can be different in every woman and with each menstrual cycle. This can impact the accuracy of urine pregnancy tests, especially in women with irregular cycles.

Where can I get one?

You can find urine pregnancy tests over the counter at most stores with a pharmacy. Be sure to check the expiration date of the test you are purchasing to ensure an accurate result. There are different types you can buy, but the key is to read and follow the instructions in the test you chose carefully. You can also schedule a free pregnancy test at Pregnancy Help Clinic, if you prefer.

Can I trust the results?

Home pregnancy tests claim to be 99% accurate. According to the Mayo Clinic, home pregnancy tests differ in their ability to find a pregnancy in people who have recently missed a period. If you get a negative result, you can retest in a week.

This can be expensive and stressful. Speaking to a trusted medical professional might be a great option. At Pregnancy Help Clinic, a medical professional can discuss the best time to test and confirm your results with a no cost quality pregnancy test and ultrasound, so you can start planning your next steps.
