A fasting specimen is preferred but not required. Collect blood in a red top tube; do not use SST tube. Immediately place on wet ice. Centrifuge, aliquot serum into a plastic vial and freeze immediately. Hemolytic or thawed specimens are unacceptable.
Place specimen on wet ice immediately following collection. Must arrive in lab or aliquot and freeze within 2 hours.
The Complement, Total Hemolytic (CH50) assay should be used as a screen for suspected complement deficiencies before ordering individual complement component assays. A deficiency of an individual component of the complement cascade will result in an undetectable total complement level. Test sent to Mayo Medical Laboratories.
