In other breeds of dogs or cats, ammonium crystals suggest liver dysfunction and portosystemic shunting. May occur with amorphous urates or sodium urate (needles or prisms) but uncommonly. Xanthine crystals, which can form after allopurinol treatment, can mimic ammonium biurate crystals (yellow-brown with small projections [ Uchiumi and Grindem ...

Ammonium urate (or biurate) crystals generally appear as brown or yellow-brown spherical bodies with irregular protrusions (“thorn-apples”). In some urine samples, they do not have irregular protrusions but have smooth borders and can resemble calcium carbonate (although these do not occur in the urine from dogs and cats).
Ammonium biurate Crystals | Medical Laboratories
Ammonium biurate crystals are yellowish-brown and can be seen in a “thorn apple” shape (round with thorny projections) or in spherical form. Chemical properties: – Clinical Significance: Ammonium biruate crystals can be seen in normal urine. – However, the presence of ammonium biurate crystals usually indicates an old or poorly preserved specimen.

Sodium urate, CaP, and calcium sulfate crystals exhibit this shape. These are very difficult to distinguish through microscopic examination and can be differentiated through the solubility test (Table 2). Sodium and calcium sulfate are usually found in acidic urine, whereas CaP is commonly found in alkaline urine. 12. TABLE 2.

2022年8月10日 · Uric acid crystals invariably form in acidic urine, typically with a urine pH < 5.5. Uric acid is soluble in alkaline urine, preventing the precipitation of urate crystals. The inability of uric acid to crystallize at urine pH > 7.0 is the rationale for urinary alkalinization in patients at risk for acute uric acid nephropathy.
