CK (Creatine Kinase)
Rapid elevations occur in myopathy and other causes of soft tissue damage, which peak within 6-12 hours of the insult. This primary muscle enzyme has a short half-life and even very high elevations can return to normal within 3-4 days. Over-interpretation of minor CK elevations should be avoided, except as a warning in cases of […]
Aspartate Transferase (AST)
Aspartate transferase (AST) is a muscle enzyme but is less muscle-specific than CK. AST has a longer half-life than CK. Because AST levels peak more slowly (24 to 48 hrs post insult) but do not revert to normal (in the absence of further insult) until 10-21 days, they are more useful in monitoring severity and […]
Serum Amyloid A (SAA)
SAA in a highly sensitive acute-phase inflammatory protein used to monitor early response to infection / inflammation and the response to treatment. Most horses have very low or zero measurable levels which rise quickly in acute inflammation. Levels rise and fall quickly with subsidence of inflammation.

Fibrinogen
Plasma fibrinogen can be measured in a variety of different ways. The modified Clauss method reference range is 0.9 to 1.7 g / l. Elevation above these ranges are very seldom seen in elite racehorses consistently performing at the highest levels. Heat precipitation method reference ranges are usually from 2 to 4 g / l […]
Sodium
Most electrolyte values seen in screening profiles lie within or very close to, reference ranges in healthy horses. They are elevated in tandem with the elevated albumin levels seen in dehydration. Significant deviations from these norms are usually seen in profound illness such as systemic illness, GIT or urinary tract disease. Sample Requirement Turnaround Time […]
