Rapid drug test only provides a preliminary analytical test result - visual - qualitative test. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result - such as gas chromatography / mass spectrometry (GC/MS) - see above. Any result taken to court, must be confirmed through quantitative tests... See similar questions...

Saliva testing has been used in scientific testing for decades and has been shown to be highly accurate. The World Health Organization (WHO) has used this method of hormone testing in worldwide comparisons of breast cancer among women living in industrialized vs. non-industrialized countries. Many studies in scientific literature have shown a strong correlation between the levels of steroid hormones in the blood stream and the "bioavailable" (free) levels of steroid hormones in saliva.

There are a variety of methods available to test for illegal substances. These methods are accurate and reliable if the following two areas of drug testing are rigidly adhered to: Use of confirmation assay. If a positive result occurs, the specimen is then tested again by a different chemical method to confirm the positive. Quality control procedures. 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...

Ketones may be measured in blood and show up approximately 2-4 hours before they will be present in the urine. In addition, with blood ketones your physician is able to get an accurate reading on your level and know when you need medical intervention. 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...

Yes, especially if you are going to have surgery to correct the prolapse, bladder testing (called urodynamics) must be done first. The prolapsed portion of your vagina may be pushing on your urethra and preventing urine leakage. If that is the case, having the prolapse corrected can give you a new problem - urinary incontinence. See similar questions...

First, it is important to note that the U.S. Department of Labor (DOL) does not regulate the area of workplace drug testing. However, it recognizes that workplace alcohol and drug abuse creates significant safety and health hazards and can lead to decreased productivity and employee morale. Therefore, DOL’s Working Partners program encourages employers to develop drug-free workplace programs, which may or may not include drug testing. See similar questions...

If you need to have surgery to correct the prolapse, bladder testing (or urodynamics) is necessary because the prolapsed portion of your vagina may be pushing on your urethra and blocking urine leakage. If so, correcting the prolapse may leave you with urinary incontinence. Urodynamics performed when holding the prolapse in its normal position will determine if you will need a continence procedure at the time of prolapse surgery. See similar questions...

With diabetes, your blood sugar can go way too high. This can occur if you overeat, take too little insulin, become sick, or are under significant stress. Under these conditions, your cells becomes starved for food and will begin breaking down fat for energy. The byproducts of fat breakdown are chemicals called ketones and can be extremely dangerous. They can make you To detect the presence of ketones, you should test your urine. Test strips for this purpose are available from Diabeticsupplies. See similar questions...

Tests are very accurate but not 100 percent accurate. Usually samples are divided so if an initial test is positive a confirmation test can be conducted. Federal guidelines are in place to ensure accuracy and fairness in drug testing programs. See similar questions...
