The D-dimer test measures the concentration of this protein fragment in the blood, which is crucial for diagnosing and monitoring thrombotic disorders. We use the Immunoturbidimetry technique to ensure accurate and reliable results.
The sample can be citrated blood or plasma/citrate. In both cases, the initial 3 mL from the venipuncture must be discarded. Send without centrifuging at a temperature between 2 - 8° C, or centrifuge and transfer to a plastic tube, preferably frozen. The sample must not show hemolysis, lipemia, or icterus.
Muestra
Option 1: Primary tube: Citrated blood 1 mL (9:1 ratio), discard the initial 3 mL from the venipuncture, send without centrifuging and at a temperature between 2 - 8° C. No hemolysis, no lipemia, no icterus. Option 2: Secondary tube: Plasma/citrate 1 mL (9:1 ratio), discard the initial 3 mL from the venipuncture, send centrifuged and transferred to a plastic tube, preferably frozen. No hemolysis, no lipemia, no icterus.
