Uric Acid
Urine pH:
Appearance:
Uric Acid
Urine pH: Acid
Appearance: Rhombic, Four-sided flat plates (whetstones), wedges, rosettes
distinguishing feature from cystine crystals
Highly birefringent
UA is Significantly increased in:
Gout, Lesch-Nyhan syndrome
Amorphous urates
Urine pH:
Appearance:
Refrigerated:
Amorphous urates
Urine pH: Acid
Appearance: Yellow-brown granules
Refrigerated: pink sediment
Amorphous Phosphates
Urine pH:
Appearance:
Refrigeration:
Amorphous Phosphates
Urine pH: Alkaline
Appearance: Similar to amorphous urates
Refrigeration: White sediment
Calcium oxalate
Urine pH:
Calcium oxalate
Urine pH: Acid/Neutral/Alkaline
type of Calcium oxalate that is (most common form)- colorless, octahedral envelope, or as two pyramids joined at their base
Dihydrate
(Ethylene Glycol “Antifreeze” Poisoning)
Monohydrate
type of Calcium oxalate that is oval or dumbbell shaped
Monohydrate
Majority of renal calculi is composed of___
Calcium oxalate
Calcium Phosphate
Urine pH:
Appearance:
Calcium Phosphate
Urine pH: Alkaline
Appearance: Colorless, flat rectangular plates, thin prisms in rosette form
Calcium Phosphate Confused with:
Sulfonamide crystals (when urine pH is in
neutral range)
to Distinguished Calcium Phosphate to Sulfonamide crystals is by:
addition of DILUTE ACETIC ACID
dissolves in DILUTE ACETIC ACID:
Calcium phosphate
do not dissolved in DILUTE ACETIC ACID:
Sulfonamide crystals
Triple Phosphate Urine
pH:
Appearance:
Triple Phosphate Urine
pH: Alkaline
Appearance: Prism shape, resembles COFFIN-LID
Triple Phosphate is also called____
“Ammonium Magnesium Phosphate”
Ammonium Biurate
Urine pH:
Appearance:

when Ammonium Biurate was Dissolves at 60degC and added glacial acetic acid it can convert into _____
uric acid crystal
Ammonium Biurate is Most often encountered in:
Old specimen (associated with ammonia produced by urea-spitting bacteria
Calcium Carbonate
Urine pH:
Appearance:
Calcium Carbonate
Urine pH: Alkaline
Appearance: Small, colorless, DUMBBELL of spherical shapes
Calcium Carbonate Resemble:_____
Amorphous material
to Distinguished Calcium Carbonate to Amorphous material is by:
addition of acetic acid (formation of gas)
Most often found in ACIDIC URINE or rarely in NEUTRAL URINE
Abnormal Urinary Crystals
abnormal urinary crystals that appeared as Colorless, hexagonal plates (Thick or thin)
