A blood test can be performed to quantify total homocysteine concentration in the plasma, of which approximately 80% is generally protein-bound. Classification of hyperhomocysteinemia is defined with respect to serum concentration as follows: [citation needed] Moderate: 15–30 nmol/mL (or μmol/L) Intermediate: 30–100 nmol/mL; Severe: > 100 ...
Such tests include crossmatching the mare's serum to washed red blood cells of the foal, which is added to exogenous complement, and is positive if hemolysis occurs. A direct Coombs test may also be used, but does have a high rate of false negatives. Crossmatching using saline agglutination does run the risk of false negatives, since some ...
Hyperhomocysteinemia has been correlated with the occurrence of blood clots, heart attacks, and strokes, although it is unclear whether hyperhomocysteinemia is an independent risk factor for these conditions. [6] Hyperhomocysteinemia has also been associated with early-term spontaneous abortions [7] and with neural tube defects. [8]
Cancer in cats is the leading cause of death among cats. It is caused by uncontrolled cell growth, and affects a wide range of cell types and organs in the body. Feline cancer initially manifests as a lump or bump on any part of the body.
Following a test for blood serum thyroxine levels thyrotropin-releasing hormone can be administered to cats intravenously and after 4 hours another blood test can be taken to measure thyroxine serum levels. If the thyroxine levels have increased this indicates the cat is euthyroid but if levels remain stagnant it suggests hyperthyroidism.
Treatment usually includes the administration of doxycycline or enrofloxacin to quell the infection along with transfusion and administration of glucocorticoids to alleviate anemia. [5] Jensen et al. 2001's PCR assay diagnoses either or both of M. haemofelis and M. haemominutum [ 2 ] [ 7 ] [ 6 ] – this is useful because they find coinfection ...
Feline idiopathic cystitis begins as an acute non-obstructive episode and is self-limiting in about 85% of cases, resolving itself in a week. In approximately 15% of cases, it can escalate into an obstructive episode ("blocked cat") which can be life-threatening for a male cat. [5]
Cats may be poisoned by many chemicals usually considered safe by their human guardians, [citation needed] because their livers are less effective at some forms of detoxification. [31] [32] Some of the most common causes of poisoning in cats are antifreeze and rodent baits. [33] Cats may be particularly sensitive to environmental pollutants. [34]
