Serum zinc and venous occlusion

Area of Science:

• Biochemistry
• Clinical Chemistry
• Trace Element Analysis

Background:

• Serum zinc is an essential trace element vital for numerous physiological processes.
• Accurate measurement of serum zinc is crucial for diagnosing and managing zinc deficiency or overload.

Purpose of the Study:

• To investigate the effect of venous occlusion on serum zinc concentration.
• To determine if a statistically significant difference exists in serum zinc levels with and without venous occlusion.

Main Methods:

• Serum zinc levels were measured in 100 healthy subjects.
• Measurements were taken both during a period of venous occlusion and without occlusion.
• Statistical analysis (p-value) was used to compare the two conditions.

Main Results:

• Serum zinc concentration was higher during venous occlusion (0.79 ug/ml) compared to without occlusion (0.75 ug/ml).
• This difference was statistically significant (p < 0.001).

Conclusions:

• Venous occlusion leads to a measurable increase in serum zinc concentration.
• Standard phlebotomy techniques involving venous occlusion may influence reported serum zinc values.
