Interpretation Of Lab Results

Blood tests Serum creatinine.     Synonym: Cr Specimen : Serum  Reference Value : 0.6 - 1.2  Method :  Spectrophotometer  Description Creatinine (kree-AT-uh-nin) is a waste product that comes from meat protein in the diet and from the normal wear and tear on muscles of the body. Creatinine levels in the blood can vary, and each laboratory has its own normal range. In many labs the normal range is 0.6 to 1.2 mg/dL. Higher levels may be a sign that the kidneys are not working properly. As kidney d isease progresses, the level of creatinine in the blood increases.  Indications Evaluated known or suspected impairment of renal function ( decrease glomerular filtration rate (GFR)

Specimen : Serum (1 ml )    Reference value : Desirable less than 200 mg/dL                              Borderline 200 - 239 mg/dL                                High Greater Than 240 mg/dL    Method : Spectrophotometer    Description :  Cholesterol is a lipid needed to from cell membranes and a component of the materials that render the skin waterproof . It also helps form bile salts , adrenal corticosteroids , estrogen and androgen .   Cholesterol is obtained from the diet (exogenous cholesterol ) and also synthesized in the body( endogenous cholesterol ) . Although most body cells can form som cholesterol , it is produced mainly by liver and intestinal mucosa .  Very low cholesterol value , as is sometimes seen in critically ill patients , can be as life threatening as very high levels .
