A 23 year old woman is admitted to the hospital in labor. A type and screen is ordered for possible caesarean section. Initial testing results are as follows:
ABO/Rh Typing
| Anti-A | Anti-B | Anti-D | Rh Control | Weak D | A1 Cell | B cell |
|---|---|---|---|---|---|---|
| 4+ | 4+ | 0 | 0 | 0√ | 0 | 0 |
Antibody Screen
| IS | 37 Degrees | AHG | CCC | |
|---|---|---|---|---|
| I R1R1 | 0 | 0 | Weak | Not tested |
| II R2R2 | 0 | 0 | 1+ | Not tested |
| III rr | 0 | 0 | 0 | 2+ |
A group O red cell panel is tested to determine the specificity of the antibody(ies). The results are given in the panel on the following page (labeled “Mom and Baby” but is the mom’s serum/plasma). Please answer the following questions using the patient results.
- What antibody(ies) is/are present?
- What antibody(ies) cannot be ruled out?
- What selected cells (if any) will be required (specifically, what antigens are present and “how” are they present)?
- Do you have enough information to determine if this patient is a candidate for postpartum Rh immune globulin prophylaxis?
- If not, what information do you require?
- If not, what information do you require?
