CHEM-20   

Overview | Risks | Results

Alternative names:

SMA20; Sequential multi-channel analysis with computer-20; SMAC20; Metabolic panel

Normal Values

Note: ALT = alanine transaminase, AST = aspartate aminotransferase, BUN = blood urea nitrogen, CO2 = carbon dioxide, gamma-GT = gamma-glutamyl transpeptidase, LDH = lactate dehydrogenase; IU = international unit, L = liter, dl = deciliter = 0.1 liter, mg = milligram, mmol = millimole, mEq = milliequivalents

Electrolytes:
Positively charged ions (cations) include sodium, potassium, calcium, and magnesium (usually drawn separately; see magnesium - serum).

Negatively charged ions (anions) include chloride, bicarbonate (essentially the same as CO2), protein (see total protein), phosphorous, SO4, and organic acids.

When an electrolyte test is performed, the measured ions usually include sodium, potassium, chloride, and bicarbonate; calcium and magnesium levels are also obtained in many institutions as part of this test.

What Abnormal Results Mean

See the individual tests.
