Group 7 â EDTA and ESR tubes. Black top ESR-Vacuum top with 3.2% sodium citrate: used for Westergren sedimentation rate. Group 9 â Yellow top with ACD Solution A. Yellow top tube with ACD (acid citrate dextrose) Solution A: used for whole blood determinations including flow cytometry and tissue typing assays.
The preferred pediatric collection container for chemistry testing is the amber SST bullet (500 ÂµL). When collecting blood specimens (venous, capillary, arterial) for chemistry testing from newborns (hematocrit greater than 50%), we recommend the use of a green top bullet with heparin (400 ÂµL). This tube type is our smallest volume blood collection tube, and will facilitate a maximum yield of plasma from whole blood. In addition, the minimum whole blood requirements listed below are based on an average hematocrit value of 50%.
