Abnormal coagulation profile
Abnormal coagulation profile (ICD-11 MA18.3) is a clinical finding of abnormal clotting tests, chiefly prolonged PT/INR, aPTT, low fibrinogen, or abnormal platelet count, reflecting factor deficiencies, inhibitors, liver disease, vitamin K deficiency, DIC, or anticoagulants.
Antigen test
An antigen test is a rapid diagnostic test that detects viral proteins in nasal swabs, giving results in 10 to 30 minutes at home or point of care.
BRAF rearrangement analysis
BRAF rearrangement analysis is molecular diagnostic testing that detects BRAF gene fusions in tumor tissue, found especially in pilocytic astrocytoma, to support cancer diagnosis and guide RAF- or MEK-directed therapy.
Chemiluminescent immunoassay
Chemiluminescent immunoassay (CLIA) is a laboratory diagnostic method that detects antigens or antibodies using a light-emitting label; first reported in 1985, it displaced radioimmunoassay and is fully automated.
Comprehensive genomic profiling
Comprehensive genomic profiling (CGP) is an oncology diagnostic using next-generation sequencing to detect many cancer-related alterations in one assay, matching targeted therapies to the tumor's genomic makeup.
Electrochemiluminescence immunoassay
Electrochemiluminescence immunoassay (ECLIA) is a laboratory binding assay in which an electrode triggers a ruthenium label to emit light, quantifying over 100 biomarkers in serum and blood.
Hair analysis
Hair analysis is the laboratory measurement of substances incorporated in the hair shaft to assess drug use, nutrition, or exposure over past weeks to months, unlike blood or urine.
Ham test
The Ham test, also called the acidified serum lysis test, is a hematology assay for paroxysmal nocturnal hemoglobinuria, developed by Thomas Hale Ham in 1939.
Indirect antiglobulin test
The indirect antiglobulin test (IAT) is a blood-bank laboratory method that detects free antibodies against red cells in serum, underpinning pretransfusion antibody screening, antibody identification, and antenatal testing.
Multi-cancer early detection
Multi-cancer early detection (MCED) is a screening approach that uses one blood test to look for signals of many cancer types at once in people with no symptoms.
Multiple electrode aggregometry
Multiple electrode aggregometry (MEA) is a point-of-care whole-blood test that measures platelet aggregation through electrical impedance between electrode pairs, used to monitor antiplatelet drugs in PCI, surgery, and trauma care.
Nasal swab
A nasal swab, also called a nasopharyngeal swab, collects mucus and respiratory cells from the nostril or nasopharynx to diagnose infections such as COVID-19, influenza, and RSV.
Peritoneal cytology
Peritoneal cytology is the microscopic examination of cells from peritoneal fluid or saline washings taken during surgery to detect free malignant cells, informing cancer staging, resectability, and treatment selection.
Prostate Health Index
The Prostate Health Index (phi) is a blood test combining three PSA forms into one score, used to estimate prostate cancer risk and reduce unnecessary biopsies.
Smear microscopy
Smear microscopy is the light-microscopic examination of stained smears, most often sputum, to detect acid-fast bacilli such as Mycobacterium tuberculosis; it remains the primary TB diagnostic in many high-burden settings.
Vaginal smear
A vaginal smear is a cytology preparation of cells scraped from the vaginal lining and examined microscopically to assess hormones, infection, and precancerous or cancerous disease.
