How do you determine the quality of blood drawn using Tasso+?
The quality of blood drawn using the Tasso+ device can be determined through several key assessments:
Visual Inspection: Examine the sample for signs of hemolysis (pink or red discoloration), clots, or contamination. A clear, uniformly colored sample indicates good quality.
Sample Volume: Confirm the collected volume (300–600 µL) meets the requirements for the intended assays.
Tube Handling: Ensure proper mixing of blood in tubes containing anticoagulants or additives (e.g., EDTA, SST) by following recommended procedures, such as gentle inversion.
Laboratory Testing: Perform quality control checks during laboratory analysis to assess sample integrity, including hemolysis, hematocrit levels, and analyte stability.
Consistency with Reference Values: Compare test results from Tasso+ samples with venous blood draws to verify reliability and accuracy. Studies have shown Tasso+ samples provide results comparable to venous draws for most analytes.
Adherence to Protocols: Follow the device’s instructions for use to ensure optimal performance and minimize potential errors during collection.
