Serum is described as hemolyzed in the presence of increased?
Lipids in a nonfasting patient
What is a form of gel-like barrier between serum and the clot in a coagulated blood sample?
serum separators
How do you obtain blood serum?
Blood serum can be obtained by collecting a blood sample from a vein and allowing it to clot. The sample is then centrifuged to separate the serum from the rest of the blood components. Serum is the liquid component of blood obtained after clotting, which does not contain cells or clotting factors.
What are the effects of lipemic sample on serum electrolyte?
A lipemic sample can interfere with the measurement of serum electrolytes by causing a falsely elevated potassium level due to the turbidity of the sample. Lipemia can also interfere with the accurate measurement of sodium, chloride, and bicarbonate levels in the serum. It is important to properly clear the sample of lipids before analyzing electrolytes to ensure accurate results.
How to obtain serum from a blood sample?
To obtain serum, the coagulated blood is left to clot at room temperature for approximately 15 to 30 minutes. After it is completely clotted, it is rimmed using an applicator stick and then centrifuged for approximately 5-10minutes at 2500 revolutions per minute. Then the supernatant fluid is separated.
If blood is allowed to clot the fluid portion of the sample is referred to?
Serum or supernatent

How are vitamin tests done?
Most of the vitamin tests are conducted by acquiring a sample of blood, and then preparing plasma or serum from the blood sample.
What is the purpose of the gel in the serum separating tube?
The gel in a serum separating tube acts as a barrier between the serum and the blood cells after centrifugation. It helps to separate the serum from the blood cells, making it easier to collect a clean sample for further analysis.
When blood is collected from patient serum should be separated from cells as quickly as possible to avoid?
When blood is collected, separating serum from cells quickly helps prevent clotting or changes in the composition of the sample due to cell degradation. This ensures accurate test results by preserving the integrity of the serum sample for analysis.
What is the purpose of gel barrier in a serum separator tube?
The gel barrier in a serum separator tube acts as a physical barrier between the serum and the clot after centrifugation. It helps to prevent the cells and clotting factors from contaminating the serum, allowing for cleaner sample separation.
