** Anticoagulant used for glucose is:
- Fluoride
**Changes in blood stored more than 5 hrs at room temp. include?
a. Decreased glucose & increased lactate.
b. Increased glucose & decreased lactate
c. Failure of Na & K pump,
- (a) Storage of blood has the following effects:
1- ↓CO2, ACP & Glucose
2- ↑pH & ammonia
3- Changes in RBC permeability →↑K,P &Mg
4- Na-K pump is inhibited at 4 °c but not at 25°c. leading to ↑K in refrigerated samples.
5- Phosphorylation→↑P released from organic P.
6- Loss of enzyme activity.
7- Light→↓ bilirubin, δALA and porphyrins.
