Reference Value for Kidney function tests



B.U.N. (Blood Urea Nitrogen)  


 Increases can be caused by excessive protein intake, kidney damage, certain drugs, low fluid intake, intestinal bleeding, exercise or heart failure. Decreased levels may be due to apoor diet, malabsorption, liver damage or low nitrogen intake.

Normal Adult Range: 7 - 25 mg/dl
Optimal Adult Reading: 16 mg/DL


                              CREATININE           

Low levels are sometimes seen in kidney damage, protein starvation, liver disease or pregnancy. Elevated levels are sometimes seen in kidney disease due to the kidneys job of excreting creatinine, muscle degeneration, and some drugs involved in impairment of kidney function, Congestive heart failure 

Normal Adult Range: 0 .7 - 1.4 mg/dl
Optimal Adult Reading:  1.05  
                      
        Interpretation 

Creatinine is formed in muscles from creatine, which is formed in the liver. It is a   substance that in health is easily excreted by the kidney. Because all Creatinine        filtered by the kidneys is excreted into the urine, its levels at any given time interval  are equivalent to the Glomerular Filtration Rate (GFR).


URIC ACID

  
 High levels are noted in gout, infections, kidney disease, alcoholism, high protein diets, and with toxemia in pregnancy. Low levels may be indicative of kidney disease, malabsorption, poor diet, liver damage or an overly acid kidney.

Normal Adult Female Range: 2.5 - 7.5 mg/dl
Optimal Adult Female Reading: 5.0
Normal Adult Male Range: 3.5 - 7.5 mg/dl
Optimal Adult Male Reading:5.5


BUN/CREATININE 

 This calculation is a good measurement of kidney and liver function. 

Normal Adult Range: 6 -25 (calculated)
Optimal Adult Reading: 15.5

MICROSCOPIC URINALYSIS

MICROSCOPIC URINALYSIS   Methodology A sample of well-mixed   urine (usually 10-15 ml) is centrifuged in a test tube at relatively low speed (about 2-3,000 rpm) for 5-10 minutes until a moderately cohesive button is produced at the bottom of the tube. The supernatant is decanted and a volume of 0.2 to 0.5 ml is left inside the tube. The sediment is resuspended in the remaining supernatant by flicking the bottom of the tube several times. A drop of resuspended sediment is poured onto a glass slide and coverslipped.

Liver Enzymes

Liver Enzymes   Definition A liver enzyme is a protein that helps to speed up a chemical reaction in the   liver. Liver function tests are blood tests that are used to evaluate various functions of the liver - for example, metabolism, storage, filtration and excretion, which are often performed by liver enzymes. However, not all liver function tests are measures of enzyme function. • ALT - (alanine aminotransferase )   - was previously called SGPT is more specific for liver damage. The ALT is an enzyme that is produced in the liver cells (hepatocytes) therefore it is more specific for liver disease than some of the other enzymes. It is generally increased in situations where there is damage to the liver cell membranes. All types of liver inflammation can cause raised ALT.    • AST - (aspartate aminotransferase) which was previously called SGOT. This is a mitochondrial enzyme that is also present in heart, muscle, kidney and brain therefore it is less specific
