| Disease Exclusion | Testing glucose for Hypo/Hyperglycemia Testing hemoglobin for anemia Testing ALT/AST for necrosis |
| Indication of Specific Therapy | Test indicate need tx with Iron, Folate, B12, or need blood transfusion or surgery |
| Monitor Therapy Effectiveness | 1. Serum Albumin/Protein for Malnutrition 2. Serum Electrolytes for Dehydration 3. Hemoglobin for anemia 4. Serum cholesterol for Hypercholesterolemia |
| Disclose Occult Disease | Stool occult Blood for colon cancer |
| Determination of Baseline Values | 1. Patient's own normal values 2. Point in time values (when was lower or higher 3. Severity of Disease (how bad is value now vs patients normal value |
| Staging of Disease | 1. Prodromal (early stage of disease) 2. Acute (rapid onset and following a short but severe course 3. Chronic (lasting for a long period of time or marged by frequent recurrence) 4. convalescence (stage marking return to health and strength after ill) |

| Normal Ranges Dependant On: | Population Demographics Environment Analytical Method |
| Population Demographics | Gender Age Ethnicity |
| Environment | Cultural aspects Geographic locations |
| Analytical Methods | Reagents Procedures Temp Analytical Variables |
| Diagnostic Sensitivity | frequency of abnormal or positive test results in individuals who have a selected disease |
| Specificity | frequency with which a normal or negative test result is observed in individuals free of disease |
| predictive value | is a measure of whether an abnormal test result really indicates that the patient has a particular disease or whether a normal test result correctly excludes the existance of a disease in the patient |
| Efficiency of test | described as the probability that a test reslt, whether positive or negative, correctly classifies the presence or absence of disease |
| %Sensitivity | = TP / (TP+FN) |
| %Specificity | = TN / (FP+TN) |
| %Positve Predictive value | = TP / (TP+FP) |
| %Negative Predictive Value | = TN / (TN+FN) |
| % Efficiency | = (TP+TN) / (TP+FP+FN+TN) |
