[Abnormal laboratory results : Plausibility, reliability, and implications].

Area of Science:

• Clinical Pathology
• Emergency Medicine
• Diagnostic Laboratory Testing

Background:

• Laboratory tests are pivotal in diagnosing patients in emergency and outpatient settings.
• Rapid medical decisions necessitate immediate evaluation and interpretation of laboratory results.
• Contextualizing test results with patient presentation is essential for accurate diagnosis.

Purpose of the Study:

• To discuss common laboratory tests for emergency patients.
• To provide guidance on interpreting these tests for clinical decision-making.
• To aid in determining appropriate patient disposition (outpatient, emergency room, or inpatient care).

Main Methods:

• Review of common laboratory tests ordered in emergency settings.
• Discussion of principles for evaluating laboratory result plausibility.
• Consideration of positive and negative predictive values in patient assessment.

Main Results:

• Laboratory test interpretation requires assessing plausibility and predictive values.
• Clinical implications of test results are paramount for patient management.
• Guidance is offered for using laboratory data to guide patient care decisions.

Conclusions:

• Effective interpretation of laboratory tests is vital for emergency patient care.
• Understanding predictive values and clinical implications enhances diagnostic accuracy.
• This guidance supports informed decisions regarding patient referral and diagnosis in outpatient and emergency settings.
