Faint line on pregnancy testFollow the instructions on the package test. Tests such as “midstream” (to use a jet of urine) may be used as a standard test (i.e., dipping in a container of urine), but then lost all of the benefits of design “midstream”. Test strip in urine stream may perhaps not be used! Urine should be collected into a clean glass, plastic or wax container, no preservative cannot add. If a test or urine stored within the refrigerator just before the analysis they need to warm up to room temperature and frozen samples will need to be completely thawed, thoroughly mixed and warm to room temperature (do not use for this stove or microwave!).What mistakes need to be avoided during the test?To the reaction zone of the test can not touch her hands.Prior to the analysis of the test must not be exposed to moisture or dirt
The test cannot be employed past the expiry date. Of course, we must not allow foreign substances within the urine sample.Strictly follow the accompanying directions to the test.Where need to be placed second strip? Does it matter if it fades?The test strips of the simplest design the upper strip control, along with the presence of HCG shows a bottom
There are tests in which the test strip forms a minus sign “-” and also the other within the presence of HCG forms with it a plus sign “. In extra complex designs tests for each strip has its own window, and cannot go wrong
The brightness of the second strip is not important; essential is the reality of its existence. Strip, regardless of the color intensity, should be located at some distance from the absorbent pad (or the edge of the window) and have a clear edge. If instead you see a clear line of pink, spot test is invalid. However, if there’s any doubt, it’s greater to repeat the test several days.Whether evidence of the test changed after some time, say, an hour after the analysis?A positive result won’t change: both stripes have been painted, and will remain
The negative results in 10 minutes or far more can appear weak second band due to water evaporation and also the release of the dye (the so-called line of evaporation). Of course, this doesn’t mean that suddenly appeared from somewhere HCG. Therefore, the outcomes obtained later than 5-7 minutes are not valid. Either a negative result won’t be positive 10 minutes or an hour later, a second strip will need to happen within the time specified on the package test (usually 3-5 minutes). However, in case you have any doubts, it’s greater to repeat the test a few days.
