Relationship between paired plasma and serum viscosity and plasma proteins in the horse.

This research article explores the relationship between the viscosity (thickness) of plasma and serum in horses and their plasma protein levels, including fibrinogen. It found a strong correlation between serum viscosity and overall serum protein and globulin levels, and also found a noteworthy association between the difference in plasma and serum thickness and fibrinogen concentration. The study additionally observed a negative correlation between albumin levels and viscosity, globulins and fibrinogen.

Understanding Plasma and Serum Viscosity

• The research examines the viscosity, or thickness, of plasma and serum in horses. Plasma and serum viscosity can influence the blood’s ability to flow, potentially affecting a range of bodily functions.
• Pairing plasma and serum viscosity measurements lead to significant findings and correlations, creating a broader understanding of these fluids’ characteristics in both normal and abnormal conditions.

Correlation between Serum Viscosity and Proteins

• A positive correlation was found between serum viscosity and total serum proteins. Essentially, as serum proteins increase, so does serum viscosity. This correlation was also sub-validated with globulin levels – a type of serum protein.

The Relationship with Fibrinogen

• Fibrinogen is a protein in the blood which helps in clotting. The difference between serum and plasma viscosity lined up well with the concentration of fibrinogen. This finding can provide key insight for when clotting might occur, with potentially far-reaching implications for predicting and treating issues related to coagulation.

Impact of Albumin Levels

• Albumin, another plasma protein, showed a negative correlation with plasma and serum viscosity, globulins, and fibrinogen. In simpler terms, when albumin levels rise, viscosity, globulins, and fibrinogen tend to decrease.

Diagnostic Value and Practical Applications

• The research concludes that simultaneous estimation of serum and plasma viscosity can enhance the diagnostic value of these tests. This approach can be both cost- and time-efficient, because it offers more information without a significant increase in expenditure or duration for the testing process.
• Such a method can be valuable for screening large numbers of samples for abnormal globulin or fibrinogen levels, enhancing early detection and preventative interventions in equine health care.
