Kidney Cells

Kidney cells are cells that cover the wall of the kidney tubules. A small number are found in normal urine. Any damage to the kidney tubules that causes separation (desquamation) of the cells on the tubule surface will manifest in a high number of kidney cells in the urine specimen (acute tubular necrosis, interstitial nephritis, proliferative glomerulonephritis).

Creatine Kinase MM (CK-MM)

CK (creatine kinase) is an enzyme (protein) found in several tissues, including muscles and the heart. Depending on the tissue, different forms of CK are present: CK-MM is primarily present in skeletal muscles, CK-MB represents 30% of CK from the heart, while CK-BB comes from the brain and smooth muscle, such as the intestinal walls. Atypical forms of CK (macro CK1 and macro CK2) can also be present. CK electrophoresis is most useful when muscular or cardiac disease does not seem to be responsible for the increased level of total CK.
