Medical Laboratory Diagnostic Services Tests&Values

Laboratory Tests Culture & Sensitivity Gram’s Stain Urinalysis Complete Blood Count Basic Metabolic Profile Lipoproteins

Culture & Sensitivity C&S Culture=identify Culture microorganism Sensitivity=isolate the Sensitivity microorganism & see what antibiotics it is sensitive to (what kills it)

Gram’s Stains help identify the microorganism so physicians can treat the pt’s infection Various stains are applied to a culture smear Gram’s stain=most frequently used stain

Urinalysis UA Evaluates sample of urine Used to detect & assess disorders, such as urinary tract infection, kidney disease & diabetes Examines appearance, concentration & content of urine

Complete Blood Count CBC Blood test used to evaluate your overall health Detects a wide range of disorders, including anemia, infection & leukemia

Complete Blood Count Can also include a blood smear Blood smear=drop of blood is spread smear thinly onto a glass slide that is then treated with a special stain Done to follow-up on abnormal CBC results to evaluate the different types of blood cells

Complete Blood Count Measures several components & features of blood, including: RBC, Hgb, Hct, WBC & thrombocytes Hemoglobin (Hgb)=determines the (Hgb) oxygen-carrying ability of the RBCs

Complete Blood Count Hematocrit (Hct)=percentage of (Hct) RBCs per total volume of blood Blood tube is placed in centrifuge & force separates blood into 3 layers=plasma, buffy coat, & packed RBCs

Complete Blood Count White Blood Cell (WBC) Count= Count body produces more WBCs when you have an infection, allergic reaction, or are under stress Leukopenia=low WBC count Leukopenia Leukocytosis=high WBC count Leukocytosis

Complete Blood Count Normal Values: Male Hgb=14 -18 gm/d. L Female Hgb=12 -16 gm/d. L Male Hct=41 -50% Female Hct=36 -44% WBC=4, 500 -10, 000 cells/m. L

Basic Metabolic Profile BMP=measures BMP 8 blood levels Measures your sugar (glucose) level, electrolytes, & fluid balance, & kidney function Includes: sodium, potassium, blood urea nitrogen, creatinine

Basic Metabolic Profile Normal Values Electrolytes: Sodium (Na) 135 -145 m. Eq/L Potassium (K) 3. 5 -5. 0 m. Eq/L Sugar: Glucose 70 -100 mg/d. L

Basic Metabolic Profile Normal Values Kidney Function: Blood Urea Nitrogen (BUN) -20 mg/d. L Creatinine (Cr) 0. 5 -1. 4 mg/d. L 7

Lipoproteins Cholesterol=waxy Cholesterol substance made by body & ingested in food; unable to dissolve in blood Lipoproteins=lipid (fat) & protein Lipoproteins complex in the blood that transports cholesterol

Lipoproteins Two types of lipoproteins carry cholesterol to and from cells Low-density lipoprotein (LDL)LDL called “bad cholesterol” because it contributes to atherosclerosis Optimal LDL = <100 mg/d. L

Lipoproteins High-density lipoprotein (HDL) HDL – called “good cholesterol” because it helps remove LDL from arteries HDL 60 mg/d. L and higher is considered protective against heart disease
