Drug test. For other uses, see Drug testing (disambiguation). A drug test is a technical analysis of a biological specimen, for example urine, hair, blood, breath, sweat, or oral fluid/salivaâto determine the presence or absence of specified parent drugs or their metabolites.
From the renal pelvis, the urine passes down a tube called a ureter which goes from each kidney to the bladder. Urine is stored in the bladder until it is passed out through the urethra when we go to the toilet. The 'cleaned' (filtered) blood from each kidney collects into a large blood vessel called the renal vein.
