Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Lavender-top (EDTA) tube
Specimens should be tested as soon as possible. Samples that cannot be tested immediately should be stored at 2°C to 8°C. Do not freeze red cells.
Gross hemolysis; bacterial or other contamination
Determine Rh type for transfusion candidates. Rh typing of expectant mothers may indicate potential for Rh hemolytic disease of the fetus/newborn. This typing is also used to determine Rh immune globulin candidacy for prenatal and postpartum patients.
Presence of potent cold autoagglutinins, positive direct antiglobulin test, and, in some cases, bacteremia may interfere with test interpretation. Variable testing results may be observed with partial antigens which are rare variants of the D antigen.
