What is the D-Dimer Test?
D-Dimer is a protein fragment produced when a blood clot dissolves. Elevated D-Dimer indicates that blood clots are being formed and broken down somewhere in your body. It's most commonly used to rule out deep vein thrombosis (DVT) and pulmonary embolism (PE) — a normal D-Dimer virtually excludes these conditions.
Why Should You Take This Test?
High negative predictive value. A normal result helps rule out DVT/PE in low-risk patients.
Who Should Get Tested?
Suspected DVT
Leg swelling, pain, redness.
Suspected Pulmonary Embolism
Sudden shortness of breath, chest pain.
Post-Surgery Clot Risk
Screening for post-operative blood clots.
