ASCP BB study plan

Build a one-page matrix of the 10 highest-yield blood group systems (ABO, Rh, Kell, Duffy, Kidd, MNS, Lewis, P, Lutheran, I) listing gene, antigens, and clinically significant antibodies for each.

Predict front-typing, back-typing, and antibody-screen results for ABO subgroups (A2, A2B, Ax, B subgroups) and weak/variant D phenotypes.

Differentiate antibody behavior by dosage, enzyme sensitivity, complement binding, and reaction phase for each major specificity.

Resolve 25 written ABO discrepancy scenarios by classifying each as technical, acquired B, subgroup, cold autoantibody, or missing/mistyped reagent.

Apply rule-out and rule-in logic to at least 10 antibody identification panels, documenting homozygous versus heterozygous cell selection.

Distinguish alloantibody from autoantibody using autocontrol, DAT, eluate reactivity pattern, and serum-to-cell ratio reasoning.

Select the correct adsorption or elution technique (autoadsorption, alloadsorption, ZZAP, LISS, PEG, acid elution) for each of 8 given scenarios and justify the choice.

Construct a workup strategy for suspected antibody to a high-frequency antigen and for a low-frequency (private) antigen, including rare reagent cell and phenotyping steps.

Write the step-by-step procedure and interpretation criteria for immediate spin, AHG tube, gel, and solid-phase crossmatch methods.

List the criteria that must be met to use an electronic (computer) crossmatch and identify which patients are excluded from it.

Apply an incompatible crossmatch algorithm that moves from clerical check to repeat typing, DAT, antibody screen, and further serologic workup.

Apply emergency release, uncrossmatched group O issue, massive transfusion protocol, and irradiation requirements to 10 clinical scenarios.

Classify acute and delayed transfusion reactions (acute hemolytic, delayed hemolytic, febrile nonhemolytic, allergic, anaphylactic, TRALI, TACO, septic, TA-GVHD) by mechanism, timing, and key laboratory findings.

Build a laboratory workup algorithm for a suspected reaction that specifies post-transfusion samples, DAT, repeat ABO/Rh, antibody screen, eluate, cultures, and imaging correlations.

Differentiate TRALI from TACO using clinical and laboratory criteria and state the donor management implications of each.

Apply hemovigilance and look-back reporting requirements, including notification timelines and required documentation for a suspected septic reaction.

Calculate the RhIG dose needed from a Kleihauer-Betke or flow cytometry fetomaternal hemorrhage result and state antepartum and postpartum dosing rules.

Interpret maternal antibody titers and middle cerebral artery peak systolic velocity values to decide on monitoring versus intervention.

Order and interpret the full prenatal and postnatal testing sequence: ABO/Rh, antibody screen and titer, cord blood typing, DAT, eluate, and bilirubin.

Compare HDFN caused by Rh, ABO, and Kell antibodies by severity, timing, and laboratory presentation.

Map each FDA-required donor infectious disease test to its assay type (serology versus NAT), approximate window period, and confirmatory or supplemental strategy.

Apply donor qualification criteria and deferral periods to 15 donor screening scenarios, including travel, medication, tattoo, and recent transfusion histories.

Explain the donor history questionnaire, physical assessment, confidential unit exclusion, and the donor reentry pathway after a reactive result.

Describe look-back investigation steps and donor notification obligations after a confirmed reactive infectious disease test.

Tabulate storage temperature, expiration, and post-manipulation dating rules for red cells, platelets, plasma, cryoprecipitate, and irradiated or washed components.

Sequence component manufacturing steps from whole blood collection through leukoreduction, irradiation, and aliquoting, noting where quality control is required.

Outline required quality control for reagents, reagents red cells, equipment, temperature monitoring, and proficiency testing, and state corrective action steps for a failure.

Differentiate the roles of FDA, AABB, CAP, and CLIA in blood bank accreditation and list record retention requirements for key records.

Complete two full-length timed practice examinations of at least 100 questions each, simulating exam pacing and flagging items for review.

Categorize every missed item by domain and root cause (knowledge gap, misread question, calculation error, unfamiliar terminology).

Re-study the three weakest domains using the error log and re-answer at least 40 targeted questions from those domains.

Recite from memory the critical thresholds and numbers tested most often: storage temperatures, RhIG dosing, deferral periods, and reaction workup timelines.
