What can cause an inconclusive pregnancy test?

Many urine pregnancy tests have positive or negative results, although the test sometimes shows none of these results, as shown in the test instructions. Yet most of the tests have a convincing result, whether it is accurate; There are also false positives and false negatives. When testing blood pregnancy, the test is sometimes read as specific, instead of positive or negative, which usually means that some levels of human chorionic gonadotropin (HCG) have been detected, but it is not enough to confirm pregnancy or too much to register as a negative result. There are many things that can be responsible for an inconclusive pregnancy test, including the timing of the test, the use of drugs for fertility or short chemical pregnancy.

The non -closive pregnancy test from the home set suggests a repetition with another test, preferably another brand. For the greatest accuracy, the test should be most sensitive to HCG levels, especially when it comes to Befruda missed periods. Tests thatThey can evaluate HCG at 20-25 million international units per milliliter (MIU/ml), most likely to detect pregnancy in an earlier stage.

There may still be problems with tests that may have more in common with how they are made; Some will only be defective. Alternatively, urine test saturation sometimes causes a test failure. For the highest quality control, repetition of a day or two later, the confusion of the inconclusive pregnancy test results usually explains, and if it is not sufficient, the test in the doctor's office or laboratory blood test may be in order.

It is important to realize that most urine pregnancy tests will not test inconclusive, except for some form of the accident. They do not try positively if they do not detect HCG at the level they are sensitive. In most cases, HCG values ​​below this amount simply produce negative reading.

forThere is also a big contrast to perform the blood test because it can measure the actual amount of HCG levels and determine the result based on a particular reading. Many blood tests see the amount of more than 1 MIU/ml to 24 MIU/ml as an inclusive pregnancy test. The presence of HCG could indicate pregnancy and usually a repetition is given in 48 or more hours.

This low amount of HCG leading to an inconclusive pregnancy test can be attributed to many things. Fertility drugs have a well -known history of false positive and inconclusive results. Very early in pregnancy, HCG levels can be very low, so low reading can be positive and the second test in a few days would confirm that it shows a higher HCG value.

Sometimes women are also briefly pregnant, but abortion occurs before the start of the next period. This is called chemical pregnancy. Testing pregnancy before a missed period could show a slight starting point of HCG, which is still an inconclusive pregnancy test.

repeatedA few days later, the test could confirm chemical pregnancy if HCG levels have dropped or do not increase. Even more rarely, growth in the reproductive tract can also create some HCG testing and inconclusive. If necessary, ultrasound may also evaluate inconclusive results, although the best values ​​are usually not accurate diagnostically, up to about five weeks to pregnancy.
