Fig. 1. Forward and reverse ABO/D typing of the patient using a gel technique with the DiaMed IH-1000 Automated Blood Screening System (Bio-Rad). Blood group was determined as: (A) A+ upon arrival, (B) A+ at 12 hr from admission, and (C) O+ at day 7 (post admission). The anti-A column is magnified in all gel cards to emphasize the change from double population (DP) to lack of agglutination.

Fig. 2. ABO genotyping based on sequence-specific primer (SSP) PCR using RBC Ready Gene ABO kit (Inno-Train DiagnostiK GmbH, Kronberg, Germany). Internal control PCR products are indicated by arrows. (A) Blood from patient upon admission; genotyping consistent with blood type A. (B) Blood from patient 12 hr after arrival; genotyping consistent with blood type A. (C) Blood from patient 7 days post admission; genotyping consistent with blood type O. (D) Patient skin biopsy; genotyping consistent with blood type O. Note: blood type A is distinguished from blood type O based solely on the “non O1” position (*) band.
