Yes, but by four: Months you should have been under the care of a physician for the sake of your and your baby's health. ...Read more
Examples are: colonoscopy for colon polyp or cancer; mammograms for breast lesions or cancer; psa a blood test that could indicate enlargement of cancerous prostate tissue; blood sugar or hemoglobin a!c for diabetes. Many think that scanning the whole body will pick up a cancer--in all likelihood, it will not. There also is no good blood test, yet, ...Read more
By not using drugs: Ethical and reputable physicians are not in the business of helping people "beat" drug tests. The sophistication of these tests have reached the point where they are difficult-to-impossible to beat, if the test is done by an experienced center which knows how people try to adulterate/substitute samples. If you have a drug problem, work on getting help rather than on not getting caught. Please!!!! ...Read more
Do early positive results on pregnancy tests indicate a higher probability of twins? I had 3 positive pregnancy tests at 3 weeks pregnant.
Not necessarily: Home urine pregnancy tests are fairly sensitive and can be positive within 9-10 days of conception. The higher the HCG (or pregnancy hormone) the more quickly it will turn positive and HCG does tend to be higher with twins...So maybe. Make an appointment with your doctor to determine. ...Read more
3 consecutive missed periods, several negative pregnancy tests. Take Loestrin 1.5/30 reliably. Pregnancy tests inaccurate? Should I get a blood test?
Not Uncommon: There are some women who may eventually stop menstruating on OCPs, especially if they have been on them for a period of time. Or, if they have some conditions like polycystic ovarian syndrome. If 3 pregnancy tests are negative, you are not likely to be pregnant. As long as you take your BCP as directed, there should be nothing to worry about. ...Read more
Going to test at the clinic, i have 8 positives and 1 negative home pregnancy tests. How accurate is the test at the clinic?
Not entirely: If positive it needs to be confirmed. If negative, you should repeat it as some people take up to a year to make enough antibodies for a positive result. If you wish to make sure, ask your doctor for an HIV nucleic acid test which would be conclusive at 4 months after exposure. ...Read more

In the U.S., yes.: Just to be clear, it's the newborn who's tested for PKU, not you. The test screens for abnormally high levels of phenylalanine in blood or urine. Since it was one of the first newborn metabolic screening tests done, it's included in newborn screening tests in this country and most others as well. However, to be certain, the mother-to-be can ask her obstetrician. ...Read moreSee 3 more doctor answers
Seek help: The baby will not test positive for meth in his/her urine, but please get help: doing meth during pregnancy can harm the baby, whether your baby tests positive or not. I'm assuming the meth is not a prescribed medication and that you are not taking this under physician's supervision.... ...Read moreSee 1 more doctor answer
Good question!: Took some research. Both hospital and home urine pregnancy tests are very sensitive. Hospital tests are generally considered more reliable but this fact was disputed in an article in the journal of Clinical Chemistry January 2014 http://www.clinchem.org/content/60/4/667.full where false negatives were found in a high number of tests from 5-7 weeks of pregnancy. A blood HCG test is most accurate. ...Read more
HCG & BCP: The pregnancy test measures HCG which is produced by an implanted embryo. The test only becomes positive about 12 days after ovulation. The hormones of the bcp do not mask a pregnancy, so if you are pregnant then the pg test will be positive. It is possible that if you do not have menses on the bcp (some women do not bleed) then you may not realize that you are pregnant or when to test. Good luck. ...Read moreSee 1 more doctor answer
