Study Notes
Clinical Diagnosis and Laboratory Testing: Key Concepts
- Diagnosis can be made through clinical signs and symptoms or laboratory tests
- Rule out or rule in disease refers to the ability of a diagnostic test to confirm or exclude a disease
- Confirm diagnosis is the final diagnosis made after receiving test results
- Therapy aims to treat, control, lessen symptoms, or cure a health problem
- Specimen collection for biochemical tests requires proper labeling and patient information
- Serum and plasma are two types of specimens collected for testing
- Hemolysis is the rupture or destruction of red blood cells and can be caused by intrinsic or extrinsic factors
- Intrinsic factors causing hemolysis include hereditary conditions and abnormalities in red blood cell structure
- A case history example demonstrates abnormal blood test results and a hemolyzed sample
- Accuracy, precision, sensitivity, and specificity are essential for analytical methods used in lab testing
- Sources of error in lab testing include preanalytical, analytical, and postanalytical factors
- Clinical specificity and sensitivity are measures of the accuracy of a test in identifying positive and negative results for a disease
