If you took a pregnancy test and it said positive but you still have you period and cramps what does that mean?
Well, since there's really no false positive tests, if your cramping and bleeding either like a normal cycle or moreso then it might be that your body is trying to reject the pregnancy and you may be miscarrying (it's what happened in my first pregnancy as well as with my SIL's ectopic pregnancy). I would see a doctor right away just to be safe.
What factor can researcher control that will reduce the risk of a type 1 error?
In statistical tests there are 2 main types of Errors, Type I and Type II. Type 1 errors occur when you reject a null hypothesis that is actually true and is thus refereed to as a false positive. Type II errors are essentially the opposite, accepting a null hypothesis that is false, and is often called a false negative. You can reduce the risk of a type I error by lowering the value of P that you're significance test must return to reject the null, but doing so will increase the chance of a type II error. The only way to reduce both is to increase the entire sample size. Alternatively, in some cases, it may also be possible to lower the standard deviation of the experiment, which would also decrease the risk of type I and type II errors.
The Difference Between a Qualitative and Quantitative Pregnancy Test?
A pregnancy test can be performed early in pregnancy to predict conception or gestational age. Urine-based pregnancy tests detect pregnancy hormones in urine for a positive or negative result. Blood tests measure how much of a pregnancy hormone is present.Qualitative Pregnancy Test – UrineHome pregnancy test kits and urine pregnancy tests given by a physician are qualitative. Qualitative refers to the method of diagnosing pregnancy. Urine tests measure the presence of human chorionic gonadotropin (hCG) in urine. If hCG is present, the test results are positive. If no hCG is found in urine, the test will be negative.False negatives are more common with a urine pregnancy test than false positives. False negatives can be caused by frequent urination due to high fluid intake and miscalculated start day of current menstrual cycle. False positives are typically linked to fertility treatments and prescription medications that include hCG as a means of increasing chance of conception.Quantitative Pregnancy Test – BloodA blood pregnancy test can be ordered as early as five to 10 days after unprotected intercourse. Blood pregnancy tests measure hCG levels in quantity rather than just a true or false result. Quantities can then be compared to normal levels as a means of gestational age prediction. In some cases, quantitative pregnant test results are higher than normal. Normal hCG levels at five weeks gestation fall between 18 and 7,340 mlU / ml. Measurements at the higher end of the range could mean medical issues with the pregnancy or multiple fetuses. Blood hCG levels will continue to rise until peaking between nine and 12 weeks gestation. After the 12th week, levels gradually fall until birth.Medical Treatment and Pregnancy TestDue to the possibility of false negative pregnancy test results, women who believe they may be pregnant should exercise caution when taking prescription and over the counter medications deemed unsafe during pregnancy. Diagnostic testing, such as X-rays and radiation-based testing should only be performed when medically necessary. Precautions include lead aprons placed over the abdominal area during X-rays. Prescription medications fall into pregnancy categories based on clinical testing and results. Categories include A, B, C, D and X.Category A drugs have been thoroughly tested for use during pregnancy and deemed safe. Category B is designated after animal testing revealed no signs of fetal harm. Category C may be linked to fetal damage in animal testing. Category D includes drugs proven to cause harm to a human fetus, but benefits from medications in this category could outweigh risks. Category X is reserved for medications that should never be used during pregnancy.
I didnt get my period last month and i took 2 pregnancy test and both came out positive What are the chances that im not pregnant?
I'm not a doctor, but I sincerely have to say "not good". The fact that both pregnancy tests say positive, as long as you did them right, then your mathematical chances are all but 100%.
Relationship between type 1 error and type 2 error?
In statistics, there are two types of errors for hypothesis tests: Type 1 error and Type 2 error. Type 1 error is when the null hypothesis is rejected, but actually true. It is often called alpha. An example of Type 1 error would be a "false positive" for a disease. Type 2 error is when the null hypothesis is not rejected, but actually false. It is often called beta. An example of Type 2 error would be a "false negative" for a disease. Type 1 error and Type 2 error have an inverse relationship. The larger the Type 1 error is, the smaller the Type 2 error is. The smaller the Type 2 error is, the larger the Type 2 error is. Type 1 error and Type 2 error both can be reduced if the sample size is increased.
I don't smoke marijuana and tested positive is that possible if I take Tylenol or advil?
Tylenol no, but Advil is famous for its ability to create false positives on marijuana tests.
Will any medicine show a false positive on a drug test?
Yes. But it won't save you, because there are more specific tests they can give that do not show false positives.

Yes it is a actual drug that is tested for in the drug test (benzodiazepines) you are taking so it's not so much a false one more as a positive one.
Can you get a negative positive pregnancy test?
It is possible. Pregnancy tests are never 100%. Depending on which one you used will depend on the accuracy of the answer. Another factor is how long it's been since your last period. False Positives and Negatives do sometimes occur though.
You have had your IUD for 7 months you have taken 2 preg tests 1 said negative the 2nd said positive what do you do?
go see your doctor. Pregnancy tests often give false negatives, but rarely give false positives. Or there could be a problem with the IUD which needs sorting.
Can riboflavin cause a false positive for THC?
Yes, Riboflavin contains vitamin B2, as well as hempseed oil, both of which can create false positives, sometimes as high as 650 ng/mL (the cutoff level for most EMIT tests is 50 ng/mL). Furthermore, Ibuprofen and Naproxen are known for causing the same false positives on these tests as well.
Is it possible to get a false positive when you take a pregnancy test at a clinic or hospital?
Yes, both false positives and negatives can happen at reliable clinics. Sometimes the reagents used for the test may be old, improperly stored or handled, causing the problem. On the other hand, home pregnancy tests are notoriously inaccurate. Anything is possible; however, they're usually always right. Sometimes home tests may not be able to detect the pregnancy hormone. If you are pregnant, congratulations, and be very happy!
