|
|
Busiest department in the lab and why?
|
Chemistry department.
The majority of common testing done here. |
|
Why is Gel Barrier important in Serum or Plasma samples?
|
Gel barrier important for stopping metabolism.
|
|
Sample Test
Serum is? color series? best tubes to use (S_T)? |
Liquid portion of clotted blood.
Red Series Gold, and Red Marble (SST) - because of thixotropic gel, after centrifugation gel separating serum from cells |
|
Sample Tests
Plasma tests - color series? Best tubes to use (P_T)? |
Lithium or sodium Hepernized
Green Series Mint, or Green Marble (PST)- don't have to wait for cells to clot, anticoag never clots. |
|
Best practice for possible pregnant pt?
|
Draw both series, Plasma and Serium. Can't use Plasma sample on pregnant pt.
|
|
Best choice series in ER?
|
PST is good choice - TAT is critical, sample not needed to clot.
