Blood Never Lies

Closer Look at Blood Samples

By George Touliatos, MD

A blood sample is divided in two main parts:

 

1) The reddish sediment that consists of RBCs (erythrocytes), WBCs (leukocytes) and platelets (thrombocytes).
2) The yellowish serum into which a plethora of components exist:
- Biochemical values
- Hormones-peptides
- Vitamins-electrolytes
- Clotting factors
- Tumor markers
- Inflammatory proteins

A low hematocrit (percentage of erythrocytes within blood) will leave a higher volume of serum. As a result, it is evitable to examine a wide variety of biochemical-hormonal labs, in case the subject is anemic. Otherwise, more blood has to be dropped.

 

A blood sample becomes hemolyzed, in the case where blood suction is wrongly performed – either by using a narrow needle or by abruptly emptying the blood sample into the bottle. Erythrocytes (RBCs) are broken down and plasma turns reddish. Under hemolysis, certain biochemical markers elevate:

- Bilirubin, potassium (K)

- Lactate dehydrogenase (LDH)

 

Bilirubin is released from ruptured erythrocytes, while LDH implies the cellular death of RBCs. The lower the hematocrit, the more the serum of blood.

Anemic patients have a larger percentage of plasma and it’s easier to evaluate the variety of biochemical and hormonal labs. On the contrary, an erythrocytotic patient has a tiny amount of plasma left on the top of the blood sample.

 

RBCs constitute the sediments of a blood sample, while plasma is on the top of it. That particular sample has a hematocrit of 20%.
