Individual tests

Copper is an essential mineral that the body incorporates into enzymes. These enzymes play a role in the regulation of iron metabolism, the formation of connective tissue, energy production within cells, and the function of the nervous system. The test helps diagnose and monitor Wilson disease, sometimes identifying a copper deficiency or excess.
The direct Coombs test detects antibodies stuck to the surface of red blood cells. Many diseases and drugs can cause this to happen. These antibodies sometimes destroy red blood cells, causing anemia. Your healthcare provider may recommend this test if you have signs or symptoms of anemia or jaundice (yellowing of the skin or eyes).
A blood alcohol test may be used for many purposes, including legal evidence, testing for alcohol poisoning, or monitoring treatment for alcohol abuse. This test also helps identify the cause of an unknown coma since alcohol intoxication can mimic a diabetic coma, cerebral trauma, or drug overdose.
Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a genetic disorder affecting red blood cells, which carry oxygen from the lungs to tissues throughout the body. The disease can cause hemolysis, where red blood cells are destroyed faster than the body can replace them.
Morphine is a substance that has analgesic properties but also causes sedation, euphoria, respiratory depression, and orthostatic hypotension. Chronic use can lead to tolerance and dependence. Clinical monitoring of compliance or illegal use measures these analytes.
