Study Notes
Purpose of Laboratory Testing
- Laboratory testing is crucial for determining appropriate patient treatment.
- Results provide information not attainable through patient history or physical examination.
Reasons for Ordering Laboratory Tests
-
Diagnosis Assignment:
- Laboratory tests assist in making differential diagnoses for vague symptoms.
- Confirmatory tests validate clinical diagnoses, such as diabetes or myocardial infarction, leading to effective treatments.
- Microbiological testing identifies specific bacteria or viruses, essential for designing treatment plans.
-
Disease Prevention and Early Detection:
- Routine screening tests help detect chronic conditions that may be asymptomatic initially.
- Early identification through tests like cholesterol levels or prostate cancer screenings improves treatment success.
- Increasing frequency of screening tests as awareness grows about benefits of early diagnosis.
-
Ongoing Patient Assessment:
- Monitoring is essential after diagnosis and treatment initiation to ensure effectiveness.
- Frequent tests, like blood draws, track therapeutic drug levels, liver function, or hemoglobin in anemic patients.
- Monitoring frequency varies based on the pathological condition; may require daily, monthly, or quarterly tests.
- Non-blood specimens may be necessary for some treatments, and repeat cultures can verify antibiotic effectiveness against infections.
