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.
