Study Notes
Laboratory Tests
- Laboratory tests are used to screen for disease, evaluate drug therapy, confirm a diagnosis, or rule out a clinical problem.
- Laboratory test results impact clinical decision-making, client assessment, and care plan revisions.
- Normal ranges are established by testing a large group of healthy individuals.
- Reference ranges can vary depending on age and gender.
- Critical values indicate life-threatening results that require immediate action.
- Post-test considerations may require follow-up assessments.
Albumin (AL)
- Normal Range: 35–50 g/L
- Indications: Diagnosing and monitoring liver diseases, impaired nutrition, chronic edema, and cancer.
- Test Explanation: Albumin is a protein made in the liver and is a component of total serum protein (pre-albumin, albumin, and globulins). Albumin maintains colloidal osmotic pressure.
- Blood Tube: Red
- Urine: 24-hour urine collection
- Purpose: Check liver and kidney function, determine if diet contains enough protein, and help determine the cause of edema in extremities and abdomen.
- Interfering Factors: Aspirin, bicarbonates, corticosteroids, salicylates.
- Lower Results: Indicative of malnutrition, liver disease, ascites, inflammatory disease, autoimmune disorder, GI malabsorption syndromes, pregnancy.
- Higher Results: Severe dehydration.
Laboratory Tests
- Lab tests are essential tools for evaluating a client's health and guiding healthcare decisions.
- They are used for screening, evaluating drug therapy, confirming diagnoses, and ruling out clinical problems.
- Lab results influence clinical decision-making, client assessment, and care plan revisions.
Normal Range vs. Reference Range
- Normal ranges are established by testing a large group of healthy individuals to determine typical "normal" results.
- Lab results must be interpreted based on context, as normal ranges can vary depending on individual factors like age, gender, and lifestyle.
Critical Values
- Critical values indicate dangerously abnormal test results that require immediate action to prevent life-threatening situations.
Albumin (AL)
- Normal Range: 35-50 g/L
- Used to diagnose and monitor liver diseases, impaired nutrition, chronic edema, and cancer.
- Albumin is a protein produced in the liver and plays a role in maintaining colloidal osmotic pressure.
- Blood sample: Red tube
- Urine sample: 24-hour urine collection
- Purpose: Checks liver and kidney function, protein intake, and causes of edema.
- Interfering factors: Drugs like aspirin, bicarbonates, corticosteroids, and salicylates can affect serum electrophoretic patterns.
Albumin Results and Significance
- Lower Levels: Indicative of malnutrition, liver disease, ascites, inflammatory disease, autoimmune disorder, GI malabsorption syndromes, pregnancy.
- Higher Levels: Severe dehydration.
Chemistry Tests
- Chemistry tests measure chemical components in body fluids and tissues to detect abnormalities.
- Common specimens used are blood and urine.
