I'm going to assume you're talking about a drug test and not a pregnancy test, because I'm not too familiar on the latter. Lol. Anyways yes, one line CAN show up on a drug test, but some factors play into it. Coke as well as some other 'party drugs' coke/X/Mollie, can be out of your system in 2-4 days, or as long as 7 or more. It really depends on your hydration level before and after you blew, the purity of the coke and your natural metabolism, and if you're a repeated user, I would say at least 3 or more times a month. If you've been clean and just did one line of average grade blow I would say with plenty of hydration, it should be out in about 3 days. One other thing to think about is that the test itself doesn't even look for the drug, it looks for the chemical your body produces by metabolizing it. That being said most employers pick only a few things to test for, because it would be just too expensive to test everyone for everything. ;) Hope that helps.
On most pregnancy tests: 1 line means: if the one line that you see is the control line, your test is negative; if the one line that you see is the test line, your test is invalid, and you must use a new test. 2 lines means: if you have two lines on a pregnancy test then your test is positive; if one line is lighter than the other, your test result is still positive.
Yes
No, One line cannot be detected after 3 days, cocaines last metabolite leaves the body 36 hours after the last administration depending on dosage. on line is not a large enough to effect it that outcome.
a faint second line is still a second line which means pregnant. take another test and if it is positive go to a doctor
Each pregnancy test kit is different in their readings. Check the label for the meaning of the one pink line to see if that represents a positive pregnancy test.
Hell no! 3 days it out!
Even if it is the faintest positive line still take it as a positive and be prepared, take another test in a couple of weeks and see if it get's darker. you never know. the faintest positive line can mean you pregnant. But like i said take another one in a couple of weeks.
One blue line means negative. Two blue lines means positive. No lines take a new test.
More than likely positive, it's just that your body does not have enough hcg hormone produced in your pregnancy yet. Wait a couple days and take another test with your first morining urine.
Take a knife cut your throat
After taking one that did not show a result @ all, then took the 2nd and it was neg. This last was a light positive line.
it has one faint line and one dark line on the other side.well, mine did and i ended up being pregnant.
