Yes. I am not sure what test you are talking about, but tests are not always 100% reliable.
The negative cable is removed first, then the positive. To re-connect, the positive goes first, then the negative.
A positive result on a Clearblue pregnancy test indicates the presence of the hormone hCG. If there is no line in the control window, the test may be defective or invalid. It is recommended to retake the test with a new one to confirm the results.
connect the positive first, the negative. the negative cable doesnt spark as much
It your test comes back "dilute negative" it is considered a POSITIVE test, because these results are a result of someone tampering with the test intself...so no free bees
It depends on the arithmetic operation you are performing:---------------------------------In AdditionNegatives and negatives have a negative sum. The only way to obtain a positive sum is to have a larger positive value than negative value.(-1) + (-2) = (-3)----------------------------In subtractionSubtracting a negative number is the same as adding its negative value (which is positive).(-1) - (-3) = (-1) + 3 = 2-------------------------------In MultiplicationThe product of two negatives is a positive. The product of a negative and a positive is negative.(-1) x (-2) = 2(-3) x (4) = (-12)------------------------------In DivisionDividing a negative by a negative yields a positive number.Dividing a negative by a positive, or a positive by a negative, yields a negative number.(-4) / (-2) = 2(-4) / 2 = (-2)4 / (-2) = (-2)By re-multiplying from the results, you can see that this holds true.
i had artificial insimination two weeks i did a blood test and its negative should i re test again my blood on my third week i have no period at all
There is a chance, but it is rare (like very rare). If your urine test comes back positive and you are sure you did not take drugs, let your employer know and ask for a re-test.
yes er re bob
Once you stop taking birth control, within 7 days of stopping it you will begin to ovulate and put yourself at risk of pregnancy. Before you re-start birth control, perform a pregnancy test. If the test is negative, you can re-start birth control. If the test is positive, see your Doctor for confirmation. When you re-start birth control, you cannot have unprotected sex until you've been on birth control for one whole month. So until this time you need to use a condom for 4 weeks.
negative 3, because on a number line, the negatives are lower when the absolute value is higher(simply stated). Basically, remember that negatives a re opposite the properties of positive.
You carry out the division ignoring the negative sign and then re-insert the negative sign. It does not matter which of the two numbers is negative. But if they are both negative, then the answer is positive.-2/3 = -2/32/-3 = -2/3-2/-3 = 2/3
False positives are very rare, less than one in a hundred positive tests are false. However with the very sensitive tests nowadays it may show up positive and then you have a very early miscarriage. Even 20 years ago tests were not that sensitive and women 'miscarried' at the time of their period without ever realising they were pregnant.
