variation in Triple phosphate crystals

Triple phosphate (ammonium magnesium phosphate) crystals are commonly seen in alkaline urine.

In their routine form, they are easily identified by their prism shape that frequently resembles a “coffin lid”.

As they disintegrate, the crystals may develop a feathery appearance.

Triple phosphate crystals are birefringent under polarized light.

They have no clinical significance; however, they are often seen in highly alkaline urine associated with the presence of urea-splitting bacteria.
