- CORD BLOOD SPECIMEN RECEIVED
Collect cord blood in a yellow top (no additive) or pink top tube. Refrigerate and send intact specimen. 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. Cord blood is the preferred specimen, however a venous sample is acceptable. Collect venous specimens in a pink top tube. Refrigerate and send intact specimen. Specimens sent for Blood Bank testing cannot be split for use by other laboratories.
Test includes: ABO, Rh, IgG Direct Antiglobulin Test, and other tests necessary to confirm or exclude the diagnosis of HDN.
