With so many pregnancy test kits on the market how do I know which one to use ?

If you have missed your period and you are looking for a pregnancy test to confirm your pregnancy then any chemist pregnancy test will do the job really well, and should hopefully give you a positive result. All modern home & professional pregnancy tests are very sensitive & accurate and false positives are rare. False negatives usually occur when the test is done too early or at the wrong time of day, so there is insufficient of the pregnancy hormone hcg in the urine sample.

If you looking for the cheapest pregnancy tests you will probably need to go online to purchase them. Pregnancy test strips are far cheaper than the leading brands of home pregnancy tests as they contain far less packaging and the technology is far simpler. You will be required to look for two lines on the test strip to confirm a positive pregnancy. They can also be bought in a range of sensitivities and can be bulk bought, if you are doing repeat or early testing before the missed period.

If you are testing early i.e. before you have missed a period , you will need to use an early detection pregnancy test kit which detects a lower level of the pregnancy hormone hcg in your urine sample. False positive can sometimes occur when you are doing very early pregnancy testing before the missed period, when you get a BFP followed several days later by a negative result or a period. This is usually referred to as a chemical pregnancy and means that for some reason the pregnancy did not continue.

Home Pregnancy Test Accuracy | Pregnancy Test Accuracy Before Missed Period

Ultra early pregnancy test strips 10mIU sensitivity

Most home pregnancy test these days have very high accuracy usually quoted at around 98-99% accuracy, if,  and this is the important bit, used according to manufacturers instructions.

What does this actuually mean ?

The quoted accuracy figures refer to clinical trials and the rate of pick up of pregnancy in pregnant womens urine, in which the level of pregnancy hormone in the urine sample is greater than the detection level of the test and where the test is being performed by someone who is familiar with the testing process. Quite often the test is being performed in a lab.

This does not mean that if you use the test it will have a 99% chance of detecting pregnancy every time. If the pregnancy is very early the pregnancy hormone (Hcg) may not be sufficiently high to give a positve result on the pregnancy test that you are using. This can cause confusion as many women are now testing for pregnancy before the missed period when the hcg levels are still very low.

Factors that affect the accuracy of the home pregnancy test:

  • whether the pregnancy test is performed correctly-make sure you read and follow the instructions that the manufacturer has provided. Not all pregnancy tests are the same and user error is common if you are not familiar with that particular brand of pregnancy test.
  • how concentrated is the urine sample-it is always best to do a pregnancy test on the urine that you product first thing in the morning on rising from bed, as this is the most concentrated. Often refeered to by doctors as the ‘1st morning void’
  • What is the sensitivity of the home pregnancy test that you are using ? The lower the mIU detection level of the pregnancy test the more sensitive is the pregnancy test ie a 10mIU pregnancy test will detect pregnancy earlier than a 25mIU pregnancy test. Some brands of pregnancy test do not disclose the detection level of the test-in this case look for a pregnancy test that says very early detection or ultra early detection if you are testing before your missed period, as these should be more sensitive than a standard home pregnancy test.
  • Make sure that you time the pregnancy test and read the result at the correct time-this varies from brand to brand so it is important to read the instructions fully before you start.

If you followed all the instrucions and the result is negative, this does not necessarily mean that you are not pregnant. It may just mean that the pregnancy hormones have not reached a sufficiently high level to give a positive pregnancy test on the particular brand of pregnancy test that you are using. If this is the case and you have not started your period then wait 48 hours (if you can ) and do another pregnancy test on a 1st morning void.

Which is the best pregnancy test ?

In my opinion the best pregnancy test currently on the UK market is the Clearblue Digital Pregnancy Test. 

 It gives the user a definite yes you are pregnant, or no your not pregnant in a digital display, leaving no room for confusion.

However all this technology comes at cost making the Clearblue Digital Pregnancy Test also the most expensive pregnancy test on the UK market (definitely the Rolls Royce of pregnancy test kits)

It can also be used up to 4 days early and the new Clearblue Digital Pregnancy Test also has a conception indicator telling you approximately when you conceived (useful if you are unsure)
