A D-dimer test is a blood test that checks for, or monitors, blood-clotting problems. A positive test means the D-dimer level in the body is higher than normal and suggests someone might have blood clots.

The AstraZeneca COVID-19 vaccine has been linked to a very rare blood-clotting disorder called ‘thrombosis with thrombocytopenia syndrome’ (TTS).
