  1. I just answered this question. My Score PASS  
  2. I've never entirely understood their purpose either. We have a commercial control which we use with our classic re-usable hemocytometers. We use a homemade stain for our counting. Yes, if a tech tends to count somewhat higher/lower than their peers they risk failing QC. This would also include variables for doing the setup such as overfilling the chamber, poorly cleaned chamber, or poor mixing(Since we use a stain). You could argue that since the QC is done once a day, that a competent tech would pass the QC, and later on a less competent tech would set up a body fluid and do i
  3. In theory the "classic" situations with acute pain are an Acute Hemolytic Reaction(as mentioned above). I have also never seen one of these practice. Have you repeated the crossmatch with the unit and a new sample? Have they done bloodwork for hemolysis markers? The pain could always be due to one of the other common transfusion reaction causes(not everything presents in textbook fashion), or not due to transfusion at all.

  5. We will test any antibody panel on receipt with a diluted version of a commercial anti-sera (Such as anti-K).

  7. 1. Babies of Rh negative moms. 2. Reflex testing from cord bilirubin >150 umol/L 3. Any others upon request. This system doesn't seem to cut down much on the amount of ABO/DAT we do on babies to Rh Positive moms since nurses will order it most of the time anyway. I would like to hear a physician's input on their reasoning behind ordering them and what the results would do to influence their clinical decision making.
  8. Haven't had to do this since I was a student so cut me some slack if I make a mistake here So we want to find out how many years "x" it takes for Company A/B to be equal. So... 275 + 6500 + 1600x = 1300 + 7000 + 1000x 6775 + 1600x = 8300 + 1000x 1600x - 1000x = 8300 -6775 600x = 1525 x = 2.54~ The question asks how many years after the initial year. Since this equation takes into account the initial year just do 2.5 years - 1 year = 1.5 years So the answer is B

  10. Our LIS prints out a requisition for the Cord whenever a baby is born. This requisition contains the mother's type and screen results.(Conveniently our LIS connects the Mother & Baby's accounts. We have Meditech and I'm not exactly sure how they do so.) The technologist then looks at the printout of every cord we get and automatically does the ABO/DAT if the mother is Rh negative. We have a comment in the mother's specimen(if she is RH negative and giving birth) that needs to be filled after the baby ABO/DAT is finished, so it will show up on our pending board until the baby specime
  11. I know some hospitals where it is done in Hematology, though here it is done in Blood Bank. I agree with Malcolm on this issue. Your calculation uses the total #counted and # of fetal cells. This is a ratio and so the calculation shouldn't change(other than you changing it to the correct number of total cells counted)
  12. Our blood bank addon printouts are formatted a bit differently than those for the rest of the core lab. There is a text entry prompt for additional requirements such as Irradiated and CMV negative. This defaults as NONE.
