Laboratory diagnostic tests are procedures performed on samples to aid in the diagnosis, monitoring, and treatment of diseases and medical conditions. These tests are conducted in clinical laboratories equipped with specialized instruments and staffed by trained professionals. They play a role in healthcare by providing valuable information about health status, decision-making, and diagnosis.
These tests encompass a wide range of techniques and methodologies tailored to detect various biomarkers, including blood, urine, tissue, and other bodily fluids or substances. Common laboratory diagnostic tests include blood tests (such as complete blood count, lipid panel, and glucose levels), urine tests (such as urinalysis and urine culture), imaging tests (such as X-rays, CT scans, and MRIs), molecular tests (such as polymerase chain reaction or PCR), and microbiological tests (such as cultures and sensitivity testing).
The results of laboratory diagnostic tests help make accurate diagnoses, monitor disease progression, and determine appropriate next steps. By leveraging advanced technologies and methodologies, laboratory diagnostic tests continue to evolve, offering improved accuracy, efficiency, and accessibility in the field of healthcare.
