Diagnostic Test Evaluation

Diagnostic test evaluation assesses how well a medical test identifies or rules out a disease. It uses measures like sensitivity (ability to detect those with the disease) and specificity (ability to correctly identify those without it). Additionally, positive and negative predictive values indicate the likelihood that a test result reflects the true condition. These evaluations help determine whether a test is accurate, reliable, and useful in clinical practice, guiding healthcare decisions and ensuring patients receive appropriate diagnosis and treatment.
