The most commonly used drug test for pre-employment is the urine test. The most common psa look for cell casts (bits of cells that normally would be removed when your blood is filtered through your kidneys) and proteinuria (protein being spilled into your body because your kidneys are not filtering the waste properly).
In conclusion, the results of this study, although not generalizable to all settings, provide valuable information on the possible cross-interference of INH and smoking status testing and how this may affect the interpretation of point-of-care urine tests.
Conclusions: These results demonstrate the utility of urine for alternative HIV-1 antibody testing and provide new insights into the pathogenesis of HIV-1 infection and into potential application of this approach in investigation of other microbial pathogens and toxic compounds.
One of the doctors overseeing Mr. Baker's urinalysis tests was Dr. Michael Ligotti, who was listed as the medical director for nine different treatment centers as of October, according to records kept by the Florida Department of Children and Families.
Pay attention to recent weight gain, renal dysfunction, facts relative to evidence of recent streptococcal infection, exposure to or ingestion of toxic chemicals (including heavy metals, carbon tetrachloride, or other organic solvents; nephrotoxic drugs).
If the skin and genital area were not cleaned well prior to collecting the sample, the urine may have lots of epithelial cells present in the microscopy and the culture may grow a number of different types of bacteria and is assumed to be contaminated.
CTU is the most comprehensive radiological method for evaluating the urinary tract for urolithiasis, renal masses, and urothelial neoplasms in a single examination.13 Cystoscopy is still required to exclude a cause for haematuria located in the bladder.
If the dipstick test or the microscopic test shows white blood cells, red blood cells, or bacteria (possible signs of a kidney or bladder infection), the doctor may send the urine to a lab for a urine culture to identify the bacteria that may be causing the infection.
There are often cases when blood in urine is not even visible; many people who have sent their samples to the laboratory to investigate other symptoms where surprised to learn about it. The more advanced stage is when urine gets a reddish or brownish color, which often seems highly alarming on discovery.

Regarding the results of examinations, for simple urine test it was observed: nitrite (yes, no), protein (yes, no), glucose (yes, no), ketone bodies (yes, no), bilirubin (yes, no), bile pigments (yes, no), blood (yes, no), leukocyte esterase (yes, no), more than four leukocytes per field (yes, no), more than two red blood cells per field (yes, no), abundant epithelial cells (yes, no) and crystals (yes, no); for urine culture (positive, negative)and isolated microorganism.
Some drugs or poisons can cause your kidneys stop functioning. Avoid getting toilet paper, pubic hair, stool (feces), menstrual blood, or other foreign matter in the urine sample. Higher levels of protein may suggest a possible urinary tract infection, or kidney disease.
