Chemistry Panel/CBC

This panel is a comprehensive blood evaluation including the following 35 tests:

Glucose, fasting: This test directly measures glucose levels and is commonly used n the evaluation of diabetes.

Normal range:	65-109 mg/dL
Optimal range:	70-100 mg/dL

Uric acid: This test is used in the evaluation of gout or recurrent urinary calculi.

Normal range:

Male:	2.4-8.2 mg/dL
Female:	2.0-6.6 mg/dL
Optimal value:	3-7 mg/dL

BUN (blood urea nitrogen): This test is used to measure liver function and indirectly to assess renal function and glomerular filtration rate.

Normal range:

5-26 mg/dL

Creatinine: This is a renal function test used to estimate glomerular filtration rate, and follow progression of renal disease.

Normal range:

Male:	0.5-1.5 mg/dL
Female:	0.5-1.1 mg/dL

BUN/Creatinine ratio: This test is used to diagnose impaired renal function. With creatinine, BUN is used to monitor patients on dialysis.

Sodium: This routine test is used to evaluate and monitor fluid and electrolyte balance and therapy.

Normal range:

135-148 mEq/L

Potassium: This routine test is used to evaluate and monitor electrolyte balance and is especially important for cardiac patients.

Normal range:

3.5-5.5 mEq/L

Chloride: This test by itself does not provide adequate information. However, as part of a multiphasic testing for electrolytes it can give an indication of acid-base balance and hydrational status.

Normal range:	96-109 mmol/L
Critical values:	<80 or > 115 mmol/L

Carbon dioxide: This test is used to assist in the evaluation of the pH and electrolyte status.

Normal range:	20-32 mmol/L
Critical values:	<6 mmol/L

Calcium: This test is used to evaluate parathyroid function and calcium metabolism.

Normal range:	8.5-10.6 mg/dL
Critical values:	<6.0 or > 13 mg/dL

Phosphorus: This test is used to measure serum phosphorus. An imbalance could indicate the possibility of any number of conditions.

Normal range:

12-60 years:	2.5 - 4.5 mg/dL
>60 years male:	2.3 - 3.7 mg/dL
>60 years female:	2.8 - 41 mg/dL

Protein/Albumin/Globulin - This test is used to assist in the diagnosis of many diseases that affect blood proteins as a whole or one single fraction of protein.

Normal range:

Total protein:	6.0-8.5 g/dL
Albumin:	3.5-5.5 g/dL
Globulin:	1.5-4.5 g/dL

Albumin/Globulin Ratio: This test is used to evaluate renal disease and other chronic disease.

Normal range:

1.1-2.5

Bilirubin: This test is used to evaluate liver function

Normal range:

Total bilirubin:	0.1-1.2 mg/dL
Indirect bilirubin:	0.2-0.8 mg/dL
Direct bilirubin:	0.1-0.3 mg/dL

Alkaline Phosphatase: This test is used to detect and monitor liver and/or bone disease.

Optimal range:

25-150 IU/L

LDH (Lactic dehydrogenase): This test measures the intracellular enzyme LDH which, when present in the blood, can support the diagnosis of injury or disease.

Normal range:

100-250 U/L

AST (SGOT): This test is used to evaluate the possibility of coronary occlusive heart disease or liver disease.

Normal range:

0-40 IU/L

ALT (SGPT): This test is used to identify liver disease and to distinguish between the liver and red blood cell hemolysis as the source of jaundice.

Normal range:

0-40 IU/L

Iron: This test is used to evaluate many disease including iron deficiency anemia and hemochromatosis.

Normal range:

Male:	40-155 mg/dL
Female:	35-155 mg/dL
Optimal range:	40-100 mg/dL

Cholesterol: This test is used to determine the risk of coronary heart disease (CHD) and hyperlipidemias.

Normal range:	100-199 mg/dL
Optimal range:	180-200 mg/dL

Triglycerides: This test is used to identify the risk of developing coronary heart disease or if fat metabolism disorders are suspected.

Normal range:	0-199 mg/dL
Optimal range:	40-100 mg/dL

HDL Cholesterol: This test measures alpha lipoprotein and is used to predict heart disease.

Normal range:	35-150 mg/dL
Optimal range:	55-150 mg/dL

LDL Cholesterol: This test measures beta lipoproteins and is used to predict heart disease.

Normal range:	0-129 mg/dL
Optimal range:	<100 mg/dL

Total Cholesterol/HDL Ratio: This test is used to determine the risk for coronary heart disease.

Normal range:	5:1 or less
Optimal range:	3.1 or less
