Specimens are unacceptable if: collected in serum separator tube, contaminated, grossly hemolyzed, of inadequate volume, or not properly labeled with patient identification. 2. Preferably cord blood, venous sample acceptable. Cord blood should be obtained by venipuncture of a cord vessel. Do not obtain specimen by squeezing the cut end of the umbilical cord since tissue thromboplastin interferes with studies.
