Exercise 1 part 2

1. Specimens for sodium, potassium, and chloride testing include serum, plasma, urine, whole blood, sweat, feces, and GIT fluid.
2. Lithium heparin, ammonium heparin, and lithium oxalate are the preferred anticoagulants for plasma specimens.
3. Ion selective electrode (ISE) is the most routinely used method for sodium and potassium testing.
4. Direct ISE is more accurate than indirect ISE for hyperproteinemic or hyperlipidemic samples.
5. Sodium is the major extracellular cation in the human body and responsible for determining plasma osmolality levels.
6. Hyponatremia is a common electrolyte disorder.
7. Heparin is the anticoagulant of choice for potassium testing.
8. High platelet count may lead to falsely elevated potassium values in serum.
9. ISE is the method of choice for chloride testing.
10. Bicarbonate is a major component of the total CO2 in the body.
