Opioid analgesics comprise a large group of substances, which control pain by depressing the central nervous system.  Large doses of Morphine can produce higher tolerance levels and physiological dependency in users, and may lead to substance abuse.  The MOP One Step Morphine Test (Urine) is a rapid urine-screening test that can be performed without the use of an instrument.  The test utilizes a monoclonal antibody to selectively detect elevated levels of Morphine in urine at a cut-off concentration of 300 ng/mL.  It comes in bulk OEM.
