    centrifugation
  5. what is plasma
    liquid portion of anticoagulated blood.
  6. plasma or serum is used more often because there is no need to wait for clotting?
    plasma is used more for this reason
  7. is plasma or serum perfect for all STAT labs
    plasma, because there is no wait for clotting
  8. does pregnancy use plasma or serum?
    serum
  9. therapeutic drug levels are tested on (plasma or serum).
    serum
  10. what kind of lab's don't need COW
    waved labs
  11. CLA '88 is
    clinical laboratory improvement act of 88 passed by congress requiring labs to register and pay a fee, and states level of complexity for labs
  12. stool cultures require
    special collection: O & P (ova and parasite
  13. O & P stands for
    ova and parasite
  14. UTI symptoms and test method
    Urine collected symptoms: burning, pain frequency and can cause kidney infection
  15. for rapid strep tests

  16. for a throat culture
    • use a cotton swab.
    • takes 2 days and tests for more bacteria
  17. how to prep a site for BC
    • alcohol scrub, then provodone-iodine allow 1 min to dry, wet iodine can cause false negative cause it kills bacteria
    • no repalpating after cleaning BC
  18. when using a butterfly draw to do a BC
    inculcate aerobic first, then anaerobic
  19. which test requires the tops of the culture bottle to be cleaned with 70% isopropyl alcohol
    Blood Culture tests (BC)
  20. when doing a syringe draw which do you inculcate first
    anaerobic then aerobic, because air is at the end of the blood in the syringe
  21. how much do we draw for a blood cultures (BC)
    always a set of 2: aerobic and anaerobicmin of 10 ml per set, at least 5ml per bottle incubated for 5 days before calling BC negative

    viruses, certain bacteria including clamydia, rickettsia and coxiella
  24. OIP is
    obligate intracellular parasite, which is a microorganism that can't reproduce outside their host forcing the host to assist in parasite reproduction
