Specimen Required

Note:    Multiple drug metabolism genotype tests can be performed

                  on a single specimen after a single extraction. See "Multiple Drug

                  Metabolism Genotype Tests" in Special Instructions for a list of

                  tests that can be ordered together.

 

 Draw blood in a lavender-top (EDTA) tube(s), and send 3 mL of

EDTA whole blood in original VACUTAINER(S).

Note:    1. Bone marrow and liver transplants will interfere with testing.

                      

                      For bone marrow transplant patients, buccal cells should

                      be provided from the recipient to obtain an accurate

                      genotype.

 

                      For liver transplant patients, donor blood or buccal cells

                      should be provided to obtain an accurate genotype for the

                      recipient patient.

2.  Transfusions will interfere with testing for up to 4 to 6 weeks.

                      DNA obtained from white cells may not provide useful information

                      for patients who received a recent transfusion of blood that

                      was not leukocyte-reduced. Wait 4 to 6 weeks until transfused

                      cells have left the patient's circulation before drawing the

                      patient's blood specimen for genotype testing.

                  3. An "Informed Consent Form for DNA Testing"

                      (Supply T576) is available. See Special Instructions

                      for a copy of the form.

                  4. UGT1A1 Test and Technology Release Physician
