Plasma or serum should be separated at the earliest for the estimation of glucose because.. The glucose values decreases with time

Plasma or serum should be separated at the earliest for the estimation of glucose because:

a. The glucose values decreases with time.
b. Glucose value increases with time.
c. Lysis of blood occurs.

a. Continued glycolysis cause glucose values to decreases with time unless cells are separated.

• Best place to put a needle for blood collection is puncture proof container.

Anticoagulant used for glucose is Fluoride - Changes in blood stored more than 5 hrs at room temp. include Decreased glucose & increased lactate

** 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.
