Trace amounts of nicotine can be detected in blood and urine for several hours, but they should be gone by 48 hours. However, if you are being tested for nicotine, there is a metabolite of nicotine, called cotinine, which can be detected in blood or urine for as long as 7 to 10 days after your last exposure to nicotine.

Because home pregnancy tests detect hCG, it is best to collect urine samples containing the highest presence of the hCG hormone. Diluted samples (from drinking high volumes of water / frequent urination) are not recommended and can diminish test accuracy. Instead, first morning urine is considered the ideal sample as it contains the most concentrated presence of hCG. Otherwise, waiting several hours (4-5 minimum) is also considered sufficient duration for an HPT. See similar questions...

A blood test is more accurate, but it depends on the type you get. Many doctors will order a simple qualitative hCG. It only gives a yes or no answer, but doesn't register your HCG levels. If you are early in your pregnancy, and your levels are low, you may get a false negative. A quantitative blood test will measure the exact amount of hCG present. It will detect even the most minimal level. See similar questions...

The length of time in which drugs can be detected is dependent on a number of variables, such as metabolic rate, dose, how it was taken, and the cutoff concentration used by the laboratory to detect the drug. No set formulas or information are available to determine this. The best practice is to not engage in the use of illegal substances. It can greatly affect your ability to get a job, keep a job, play sports, or succeed in whatever life event requires you to be drug tested. See similar questions...
