Which of the following is caused by excessive shaking of a tube?

Rationale

Hemolysis is caused by excessive shaking of a tube.

Excessive shaking of a blood sample tube can lead to hemolysis, which is the destruction of red blood cells, causing the release of hemoglobin into the surrounding plasma. This can interfere with laboratory test results and is a common issue in sample handling.

A (Hemophilia) YOUR ANSWER

Hemophilia is a genetic disorder that affects the blood's ability to clot due to the absence of specific clotting factors. It is not caused by mechanical actions such as shaking but rather by inherited deficiencies in the blood's coagulation cascade.

B (Hemoconcentration) YOUR ANSWER

Hemoconcentration occurs when the concentration of blood cells increases due to a decrease in plasma volume, often a result of dehydration or fluid loss. This condition is not directly related to the mechanical disruption of blood samples, making it an incorrect choice.

D (Hemostasis) YOUR ANSWER

Hemostasis is the process of blood clotting and the cessation of bleeding. It involves a complex interaction of platelets, clotting factors, and blood vessel responses. This physiological process is unrelated to the effects of shaking a tube, as it pertains to the body's response to injury rather than sample preparation.

Conclusion

Hemolysis is the only option that directly results from excessive shaking of a blood tube, leading to the rupture of red blood cells. In contrast, hemophilia, hemoconcentration, and hemostasis involve underlying physiological processes or conditions that are not influenced by mechanical agitation. Understanding these differences is crucial for accurate laboratory practices and ensuring the reliability of diagnostic tests.
