Have you got a very faint line in the pregnancy test and apprehensive about the conception? Sometimes due to irregular menstrual cycles. When a faint line appears in the pregnancy test after designated time of reaction in a test it means this is an evaporation line. In a pregnancy test a faint line means a positive result for pregnancy. But this should be appreciated in 5 to 10 minutes. However the test has to be conducted in an appropriate way to ensure the faint line is observed in the time frame to ensure the weak faint line is indicative of a positive pregnancy test. A very faint line on pregnancy test may be due to several reasons. One of those reasons is the test is performed too early. In early tests the HCG may not be sufficient to be detected and hence results in a very faint line. different tests performed show different reactions because of different HCG levels.Sometimes the urine sample is diluted due to frequent urination or extra intake of fluids. This may also result in a very faint line in a  pregnancy test. Sometimes due to a miscarriage at a later stage of implantation may result in a very faint line. it is always advised to read the pregnancy test within the advised time limits to be sure about the results of the test. The evaporation lines appear to show that the composition of urine is showing up. This might appear in any test regardless of any particular significance. In a pregnancy test depending on the hCG level the different color bands appear. In case of appearance of a very faint line in a pregnancy test the test might be conducted again to ensure that there is pregnancy. However with a retake of the test for multiple time there will be different band lines and that is interesting to observe such changes. However a second opinion from another laboratory might be sough to ensure that the very faint line in the pregnancy test is indicative of the fertilized embryo. Though sometimes chemical pregnancy may result in a nullified effect later , or may be due to a very low hormonal level that might show a different band of line. it is always advised to go for trusted diagnostic centres and in case of any doubt , the test should be taken again. A very faint line on pregnancy test may create confusion in the mind of the test taker however most of the times it is a positive result
