It is a known fact that no method of birth control is absolutely foolproof, and all it takes for someone to get pregnant is a single sperm! With that given, if you are someone who is sexually active, even a delay of a day or two in the arrival of your period can make you panic. The first thought one would have is probably that of a pregnancy. Whether or not you are hoping for it, you would definitely want to know what is going on with your body. And that is exactly what an at-home pregnancy test kit was invented for!
Here are a few things you should know about pregnancy test kits before you use one-
1) How they work
All at-home pregnancy test kits work by detecting a hormone called human Chorionic Gonadotropin (hCG) in the urine. This hormone is produced by the developing placenta after fertilization takes place. The fiber strip of the test is coated with a chemical that reacts with hCG to change colour and produce result. Here are a few tips that you should keep in mind while using hCG kits:
- An hCG kit should be stored between 4° C to 25° C for maintaining shelf life. Preferably, it should be refrigerated before use.
- It should be brought to room temperature before use.
- Some brands claim higher accuracy than the others, which might not be necessarily true. What does affect the quality of the pregnancy test kit is the way it is stored. The result will not be accurate if the kit is faulty, damaged or expired. Thus, it is advised that you buy the kits from a store that actively sells and restocks pregnancy test kits.
- Avoid any form of liquid intake before testing for pregnancy.
2) There is a slight chance of inaccuracy
Most pregnancy test kits claim to be about 99% accurate. However, under certain conditions, the results might be imprecise. There can be two case scenarios when it comes to inaccurate results; it could either be a false positive or a false negative. The latter out of these two is more likely to happen. For example, if you are testing too early in your pregnancy, the kit might say ‘negative’ even if you actually are pregnant. This might happen due to the fact that that your hCG levels are not high enough to be detected. Also, consumption of excessive amounts of fluid before testing may dilute the urine, producing inexact result. To avoid these kinds of situations, it is advised that you take the test a day or two after the missed period, since the hCG levels would have risen to a detectable point.
False positives occur very rarely. These might occur in the case of ‘biochemical pregnancy’ wherein the chemical imbalance in the body causes the hCG levels to rise and give the false impression of a pregnancy. Similarly, ‘ovarian tumour’ can cause the secretion of hCG which can be the reason behind a false positive test result. In some cases, false positives can occur in the case of early miscarriage of pregnancy wherein traces of hCG would be left behind but there would be no living embryo. Consumption of fertility drugs which induce higher levels of hCG also might cause false positive results.
To get accurate results, one has to take multiple tests(preferably 2-5) at different time intervals. If your test turns out to be negative but you still haven’t received your period, you might have to take another test a week later. Although the test can be taken during any time of the day, it is said that the best time to test is early morning as the urine is more concentrated and hormones levels will be higher, and thus sensitive to detection.
3) There are different types of pregnancy test kits
There are a few variations of pregnancy test kits available in the market. These include-
- Standard kits: These are the ones that show results by changing color of the strip.
- Digital kits: These pregnancy test kits have a screen on which printed letters that either read out ‘pregnant’ or ‘not pregnant’ appear. Some of them use other symbols which are usually mentioned on the instructions leaflet. Digital tests are more expensive than standard kits but are more accurate and facilitate the clear reading of results which the standard kits sometimes fail to provide one with.
Variations also exist in the way urine is collected by the kit. While the most common type of pregnancy test kit comes with a test strip or dipstick, a few brands also offer a second type which comes with a urine collection cup.
4) There is a difference between ovulation predictor kits and pregnancy test kits
Ovulation predictor kits and pregnancy test kits work in different ways. While the former observes an increase in the luteinizing hormone, which occurs before a woman ovulates, the latter looks for increase in HCG levels. Although ovulation predictor kits are used by women to test whether they are ovulating or not, they can also be used as pregnancy test kits because both of these hormones work similarly in the body. However, if you decide to use an ovulation predictor kit to detect pregnancy, it would be better to confirm the result by using a pregnancy test kit itself.
5) Timing matters!
If you’re going to the chemist to buy a pregnancy test, chances are, you want an answer ASAP. But earlier isn’t better when it comes to reliability since HCG doubles every 48 hours. It is recommend testing no sooner than a day or two before your missed period – if not the day of – to allow your body enough time to accumulate HCG in the case that you are pregnant. Even then, there’s room for error since your body may secrete HCG later or more slowly than average.
Whenever you decide to test, boost your chances of detecting HCG by taking it first thing in the morning when your urine is most concentrated.
Timing is equally important when you’re waiting for the test to develop so wait for complete time to know the exact results. If the package says two minutes, then you really have to wait the full two minutes before you know.
How soon should you take the test?
You should wait to take a pregnancy test until the week after your missed period for the most accurate result.
If you don’t want to wait until you’ve missed your period, you should wait at least one to two weeks after you had sex. If you are pregnant, your body needs time to develop detectable levels of HCG. This typically takes seven to 12 days after successful implantation of an egg.
You may receive an inaccurate result if the test is taken too early in your cycle.
