Horses in hard training may need a vitamin E supplement, as their requirements are higher than horses in more moderate work. The horse may also be deficient in selenium, and need a feed in supplement. Selenium can be dangerous if overfed, so a blood test to confirm that the horse is in need of supplemental selenium should be used. [1]
Simply put, an ELISA test is a variant on the home pregnancy test technology. It requires a drop of urine, can be performed relatively rapidly, is highly sensitive, and test results can be read by eye. Initially, the ELISA tests were "one-step" tests meaning that urine was added to the test well followed by the addition of antibody for the test.
One of the measures of kidney function is the glomerular filtration rate (GFR). Other tests that can assess the function of the kidneys include assessment of electrolyte levels such as potassium and phosphate, assessment of acid-base status by the measurement of bicarbonate levels from a vein, and assessment of the full blood count for anaemia.
The fractional excretion of sodium (FE Na) is the percentage of the sodium filtered by the kidney which is excreted in the urine.It is measured in terms of plasma and urine sodium, rather than by the interpretation of urinary sodium concentration alone, as urinary sodium concentrations can vary with water reabsorption.
A diagnosis of rhabdomyolysis may be suspected in anyone who has sustained trauma, crush injury or prolonged immobilization, but it may also be identified at a later stage due to deteriorating kidney function (abnormally raised or increasing creatinine and urea levels, falling urine output) or reddish-brown discoloration of the urine.

Renal compensation is a mechanism by which the kidneys can regulate the plasma pH. It is slower than respiratory compensation , but has a greater ability to restore normal values. Kidneys maintain the acid-base balance through two mechanisms: (1) the secretion of H + ions into the urine (from the blood) and (2) the reabsorption of bicarbonate ...
A fluid or water deprivation test is a medical test [1] which can be used to determine whether the patient has diabetes insipidus as opposed to other causes of polydipsia (a condition of excessive thirst that causes an excessive intake of water). The patient is required, for a prolonged period, to forgo intake of water completely, to determine ...
Water makes up between 62-68% of a horse's body weight and is essential for life. [15] Horses can only live a few days without water, [14] becoming dangerously dehydrated if they lose 8-10% of their natural body water. [15] Therefore, it is critically important for horses to have access to a fresh, clean, and adequate supply of water. [citation ...
