Faint line on pregnancy testFollow the instructions on the package test. Tests for example "midstream" (to use a jet of urine) could be utilized as a standard test (i.e., dipping in a container of urine), but then lost all of the advantages of design "midstream". Test strip in urine stream may possibly not be used! Urine really should be collected into a clean glass, plastic or wax container, no preservative can not 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 need to be completely thawed, thoroughly mixed and warm to room temperature (do not use for this stove or microwave!).What mistakes should be avoided during the test?To the reaction zone of the test can not touch her hands.Prior to the analysis of the test really should not be exposed to moisture or dirt
The test cannot be used past the expiry date. Of course, we really should not enable foreign substances inside the urine sample.Strictly follow the accompanying directions to the test.Where must 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 "-" plus the other in the presence of HCG forms with it a plus sign ". In extra complex designs tests for each strip has its own window, and can not go wrong
The brightness of the second strip is not important; important is the fact of its existence. Strip, regardless of the color intensity, will need to 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 is much better to repeat the test several days.Whether evidence of the test changed after some time, say, an hour after the analysis?A positive result will not change: both stripes have been painted, and will remain
The negative outcomes in 10 minutes or far more can appear weak second band due to water evaporation as well as 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 results obtained later than 5-7 minutes aren't valid. Either a negative result will not be positive 10 minutes or an hour later, a second strip should happen within the time specified on the package test (usually 3-5 minutes). However, should you have any doubts, it really is much better to repeat the test a few days.
