| What steps of QA is analytical? |
Specimen processing/testing/reporting |
| What steps of QA is post-analytical? |

| What are the 4 tubes commonly used for Chem tests? |
Grey (plasma). ***SST (serum)***Green, heparin (plasma)****Red, none (serum) |
| Is plasma and serum intercellular fluids or extracellular fluids? |
Extracellular |
| What is the difference between Plasma and serum? |
Plasma contains fibrinogen. Serum does NOT contain fibrinogen. |
| Give three reasons a specimen is deemed unacceptable. |
Hemolysis-breakage of RBCs. Gycolysis-sits too long before separation. Improper collection. |
| Potassium is a major intracellular component. Why is that important to know as a phlebotomist? What can happen? |
Hemolysis breaks the RBC and K (potassium) is released to the plasma.A high number indicated heart attack. |
| What are common electrolytes? |
Sodium, potassium, chloride, COs |
| What are some common causes of Hemolysis? |
difficult draw. Forcing blood through small needle(syringe). Specimen handling (shaking)transport issuesmix w/ iv drips |
| Define glycolysis |
breakdown of sugar |
| What happens to a blood sample that does not get centrifuged in a timely manner? |
glycolysis continues, and the glycose levels decrease at a rate of 2-3% per hour. |
| give 3 examples of how to prevent glycolysis. |
Use grey top tube. Additive will stop the breakdown.**Separate quickly.**Use SST tube and separate. |
| Give a common test for the Pituitaty glands. |
TSH |
| Give a test example for the Thyroid. |
T4, TSH |
| Give an example of a test involving the Parathyroid. |
Calcium |
| Give and example of a blood test for the lungs. |
CO2 |
| Give an example of a test for the heart. |
Na (sodium)--- K (potassium)---CKMB (creatnine)--- Trop (troponin) |
| Give some examples of tests for the liver. |
Bilirubin, ALT, AST, GGT, Alk Phos |
| What is a common test for the adrenal glands? |
Cortisol |
| Give 2 test common for the pancreas. |
Amylase, Lipase |
| What are some tests usually associated with the ovaries? |
HCG, FSH, LH |
| What are some tests usually associated with the testes? |
HCG, testosterone |
| What are some common therapeautic drugs that are monitored by blood tests? |
