Transfusion medicine checklist: Record and other requirements updated in new release

August 2018—One new requirement and several modified requirements in the CAP transfusion medicine checklist are part of the new edition of CAP accreditation program checklists released this month. In work led by the CAP Council on Accreditation, the checklists are examined anew and revised yearly, where needed. In transfusion medicine, the changes this year center on computer crossmatches, record retention, forward/reverse typing, and ABO group and Rh(D) type verification.

With hemolysis, tackling the rush with the reasoning

May 2018—First a journey. Then sometimes a vigorous shake. Little wonder that red blood cells hemolyze. “Red blood cells don’t like to be stressed,” says Kathleen Finnegan, MT(ASCP)SH, phlebotomy training program director at Stony Brook University School of Technology and Management, New York. She instructs her students to avoid stressing the RBCs by skipping what she calls the “martini shake” (CLSI recommends five to 10 tube inversions), using a needle that is the right size, and not using a syringe for transfer but instead a transfer device. “So it’s gentle,” she says.

AABB seeks comments on form to streamline transfusion adverse reaction reporting

January 2018—The AABB is seeking comments by March 30 on its common transfusion reaction reporting form, the seven pages of which are presented online at www.bit.ly/AABB-reportform. The fillable PDF form is intended to be used by hospitals and blood centers to communicate information about transfusion reactions to the blood supplier, particularly when there are multiple suppliers to the hospital transfusion service.

New rays on blood safety

March 2017—The language of blood banking experts, as they talk about irradiators, transfers easily to a car dealership. How reliable are the newer models? Are you willing to replace it every 10 years or so? Do you keep running it until it dies? What parts are likely to burn out? What will repairs run? And then the word “terrorism” pops up.

Blood bank: On guard against daratumumab interference

October 2016—As fans of spycraft know, offensive counterintelligence can include an arsenal of strategies: initiating a diversion, sowing confusion, creating false identities—anything that makes another party believe something that isn’t true. If the cancer treatment drug daratumumab were capable of deceptive intent, it might be accused of all those ploys when it comes to interfering with blood transfusion crossmatching. The reason: For patients receiving daratumumab, marketed as Darzalex by Janssen Pharmaceuticals, antibody testing for transfusion is subject to erratic false-positives, often leaving transfusion services confused, uncertain, and on hold.

Mislabeling, wrong-blood-in-tube errors rare but there

November 2015—Blood is thicker than water, the saying goes. And thanks to a recent Q‑Probes, the rates of mislabeled specimens submitted for ABO blood typing and of wrong-blood-in-tube errors are now as clear as water. The mislabeling rate hasn’t changed much since a similar Q‑Probes study was performed in 2007. The 2015 Q‑Probes, “Blood Bank Safety Practices,” reviewed 41,333 specimens and found that 306, or 0.74 percent, were mislabeled. The previous study looked at 112,112 specimens, of which 1,258, or 1.12 percent, were mislabeled.

Groups urge phase-in of RHD genotyping

October 2015—It may not be quite like boxing frogs or herding cats. But gaining broad consensus on a laboratory medicine practice can be difficult, especially where multiple organizations must agree. A new joint statement on RHD genotyping by the CAP and the AABB, plus four other organizations, shows that such consensus is possible, however, even where it involves a laboratory medicine practice in place for more than 50 years—especially when advances in molecular testing are offering a solution to a problem.
