Front

What is hemolysis?

Back

Hemolysis is the breakdown of red blood cells, leading to the release of hemoglobin into the surrounding fluid, often indicated by a pink or red appearance in a gel microtube.

Front

What does a mixed field reaction indicate?

Back

A mixed field reaction occurs when there are two or more populations of red blood cells present, often due to the presence of different blood types or conditions affecting the blood.

Front

What is the significance of grading a reaction as 1+?

Back

A 1+ grading indicates a weak positive reaction, suggesting a low level of agglutination or hemolysis.

Front

Why is it false that all gel cards can be stored at room temperature or refrigerated?

Back

Different gel cards have specific storage requirements to maintain their integrity and functionality, and not all can withstand the same temperature conditions.

Front

What can cause a mixed-field reaction appearance in samples?

Back

Samples containing strong, direct agglutinating antibodies can cause a mixed-field reaction appearance due to the clumping of red blood cells.

Front

What is the role of centrifugation in blood testing?

Back

Centrifugation separates blood components based on density, which is crucial for accurate testing and analysis.

Front

Define 'rouleaux' in the context of blood samples.

Back

Rouleaux refers to the stacking of red blood cells, resembling a stack of coins, often seen in certain pathological conditions.

Front

What does a 4+ grading indicate in blood testing?

Back

A 4+ grading indicates a strong positive reaction, showing a high level of agglutination or hemolysis.

Front

What is the importance of proper centrifugation in blood tests?

Back

Proper centrifugation ensures the separation of blood components is effective, preventing misinterpretation of results due to improper sample preparation.

Front

What is the appearance of a top line reaction?

Back

A top line reaction is characterized by a distinct line at the top of the gel microtube, indicating a specific reaction or result.
