It can be unsettling to take a home pregnancy test if you have doubts about the accuracy of the results.
Women use an ovulation test kit to determine when they are fertile. It helps pinpoint the window of fertile opportunity within a woman’s monthly cycle.
A rise in luteinizing hormone (LH) in the urine is what this test looks for. When this hormone rises, the ovary knows it’s time to deliver an egg. Numerous women rely on the results of this at-home test to estimate the time of their next ovulation. Pregnancy is most likely during this time. Most drugstores sell these kits (source).
Learn the best times to take a home pregnancy test and how to avoid common errors.
What Is The Best Time To Take A Pregnancy Test At Home?
The first day of a missed period, or even earlier, is said to be the cutoff for the majority of home pregnancy tests.
However, you may obtain more reliable results if you wait until after the first day of your missing period.
So, why hold off? Almost immediately after a fertilized egg implants into the uterine lining (implantation), the placenta develops and begins secreting human chorionic gonadotropin (HCG).
Ingesting this hormone causes it to pass into blood and urine.
The HCG level doubles every two to three days in the early stages of pregnancy.
The earlier in the pregnancy you try to take a home pregnancy test, the less likely it is that the test will be able to detect HCG.
It’s important to remember that ovulation can occur at different times each month and that the fertilized egg can implant at different times in the uterus.
Since this might delay or speed up HCG production, it may also delay or speed up its detection.
If your periods come and go at odd intervals, you may frequently be caught off guard.
Your doctor may advise an ultrasound, a second pee test at a lab, or a blood test to determine your HCG levels if they feel you must confirm your pregnancy.
Most tests involve inserting the tip of a dipstick into a stream of urine or dipping the stick into a collection cup.
A positive or negative result, one or two lines, or the words “pregnant” or “not pregnant” appear on a strip or screen a few minutes after the dipstick is inserted.
Before examining your results, wait the recommended time (typically two minutes or more).
The control indicator, typically a line or symbol in the results window, is present in most examinations.
The line or symbol must be displayed for this test to be valid.
Conduct yet another trial.
There is a wide range of sensitivity among home pregnancy tests. This means that some tests have a lower cutoff level of HCG in the urine before they return a positive result.
To What Extent Are Home Pregnancy Tests Accurate?
Numerous at-home pregnancy tests advertise an accuracy rate of 99 percent or higher.
However, the accuracy with which home pregnancy tests may detect pregnancy in women who have recently missed their periods varies widely.
If a pregnancy test returns negative, but you’re still worried, you can take another one a week following your missing period or consult your doctor.
Is There a Chance That Your Medicine Will Affect Your Test Results?
Results from a home pregnancy test may be impacted by the use of fertility medicines or other treatments containing HCG.
However, the effectiveness of home pregnancy tests is unaffected by most drugs.
Could A Correct Result Even Be A Positive One?
A false positive result on a home pregnancy test is doubtful to occur unless the test is poorly calibrated. A false-positive result would describe this.
You may get a false positive if you take a pregnancy test too soon after using a fertility treatment containing HCG or if you experience a miscarriage shortly after the fertilized egg attaches to the uterine lining (biochemical pregnancy).
Possible causes of false positive results include ectopic pregnancy, menopause, or issues with your ovaries.
Do We Have Any Reason To Doubt That A Negative Outcome Is Correct?
Even if you’re pregnant, a home pregnancy test could be harmful.
We call this a “false-negative” result.
When testing for something, you could receive a false-negative result if you:
· Do not show up to the exam too soon.
Taking a home pregnancy test sooner after missing menstruation makes it more difficult for the test to detect HCG.
If you miss your period, you should retake the test a week later for the most reliable results.
If you feel you cannot wait that long, it is recommended that you request a blood test from your doctor.
· Prematurely analyzing test results.
Please be patient while the test completes. Depending on the instructions, you may want to use a timer.
· Use diluted urine.
Take the test first thing in the morning, when your urine is most concentrated, for the most reliable results.
The Next Step Is?
You may want to do the following in light of your test results:
- You’ve taken several home pregnancy tests with positive findings or one or more with conflicting results.
You should see a doctor, so schedule an appointment. In order to confirm your pregnancy, you may need to get blood work or an ultrasound. Early pregnancy confirmation allows for earlier initiation of prenatal treatment.
- The results would have been negative if you had taken a pregnancy test at home.
If you took the test right before or after a missed period and your period still hasn’t started, you should retake it in a few days or a week.
- You’ve had repeated negative pregnancy tests, but your period hasn’t started, and/or you’re still wondering if you’re pregnant.
You should talk to your doctor about this. Amenorrhea is the medical term for lack of menstruation, and several circumstances can cause it. If you’re not expecting a baby, your doctor can help you get your period back on schedule.
