Quick Fix Synthetic Urine is the clean, pre-mixed laboratory urine that everyone is talking about! Quickfix synthetic urine The truth is that some drug testing labs have the ability to detect synthetic Urine.  I am no biologist or doctor but I believe they can know that a urine sample is synthetic by the absence of certain substances contained in Urine from a normal healthy person.   Unless the Synthetic urine can also be made to contain those same substances, there is no guarantee you will pass that drug test with the Synthetic urine.  I have heard that Synthetic urine fails only if they have to test for Uric Acid which certain labs in only Oregon or Washington do. There is 1 person that has lost a 7 year job because the lab found out he used synthetic urine.  Below is what he was told. “We are calling you to notify you that you used synthetic urine and or a substitution for your drug test, so you will need to talk to your employer about that.” By chemical analysis: Here is a list of all substances contained in normal regular Human urine: Non-organic substances in the urine: bicarbonate, chloride, phosphorus, sulphur, bromide, fluoride, iodide, rhodanide, potassium, natron, calcium, magnesium, iron, copper, zinc, cobalt, selenium, arsenium, lead, mercury.  Nitrogenous substances in urine nitrogen, urea, creatine, creatinine, guanidine, choline, carnitine, piperidine, spermidine, dopamine, epinephrine, norepinephrine, serotonin, tryptamine, levulinique amino-acid, bilirubin, and so on.  Amino acids in the urine: alanine, carnosine, glycine, histidine, leucine, lysine, methionine, phenylalanine, serine, tyrosine, valine, hydroxyloproline, galactosylhydroxylyzine, xylosylserine, and others.  Protein in the urine: albumin, haptoglobin, transferrin, immunoglobulins IgG, IgA, IgM, and others.  Enzymes in the urine: lactadehydrogenase, gamma-glutamyl transferase, alpha amylase, uropepsinogene, lysozyme, beta-N-acetylglucosaminidase, urokinase, protease, and others.  Carbohydrates (sugars) in the urine: arabinose, xyloseribose, fucose, rhammose, ketopentose, glucose, galactose, mannose, fructose, lactose, sucrose, fucosylglucose, raffinose, and others.  Substances devoid of nitrogen in the urine: wide assortment of organic acids  Vitamins in urine: thiamine (vitamin B1), riboflavin (vitamin B2), vitamin B6, 4-pyridoxique acid, nicotinic acid, vitamin B12, biopterine, ascorbic acid (vitamin C) and others.  Hormone in urine: gonadotropin, corticotropin, prolactin, lactogeniques hormones, oxytocin, vasopressin, thyroxine, catecholamines (epinephrine, norepinephrine, dopamine), insulin, erythropoietin, corticosteroids (aldosterone, corticosterone, cortisone), testosterone, progesterone, estrogen and others.
