Red Blood Cell Flexibility Test

California rates for HCPCS 0305U

Measures how readily red blood cells bend and change shape when they are pushed along under flow, which is what allows them to squeeze through the body's smallest vessels. A whole blood sample is tested under shearing force and the result is reported as an index value. Companion tests in the same set measure how strongly red cells stick to a surface rather than how easily they deform.
