A) Repeat the ABO grouping on the incompatible unit using different sera B) Do a panel made up of red cells having all low-frequency antigens C) Perform a direct antiglobulin test (DAT) on the donor unit D) Obtain a new specimen and repeat the minor cross match correct answersC Recovered from a sputum sample, this suspicious form measures 112 micro meters by 55 micro meters. Please select the single best answer A) Schistosoma mansoni egg B) Paragonimus westermani egg C) Pneumocystis carinii cyst D) Diphyllobothrium latum egg correct answersB Illustrated in the photomicrograph is the tail portion of an adult worm of a filarial nematode.

These adult worms measure up to 300 um, occupy lymphatic channels and may cause lymphatic obstruction. Varying degrees of fever and chills may be experienced. The species indicated in this exercise by the orientation of nuclei within the tail section (arrows), more commonly involves the lymphatics of the genital tract resulting in orchitis and hydrocele. From the nematode species listed below, indicate the most likely species identification. Please select the single best answer A) Brugia malayi B) Wuchereria bancrofti C) Loa loa D) Dirofilaria immitis correct answersB Which one of the following red blood cell phenotypes will NOT react with Anti-Fy3?
