Diagnosis of CAT involves a combination of clinical assessment and diagnostic tests. Symptoms such as swelling, pain, and redness in the extremities can indicate deep vein thrombosis, while sudden shortness of breath or chest pain may suggest a pulmonary embolism. Diagnostic tools include:
D-dimer test to measure clot-degradation products in the blood. Ultrasound imaging to detect clots in the veins. CT pulmonary angiography for detecting pulmonary embolism.
