A patient had the following urine chemistries. Upon performing the microscopic Triple Phosphate crystals were easily identified with the alkaline pH. However, another type of crystal was noted that took the form of wheat sheaves and needles. Looking in the reference books, it looks like the crystals for medications such as ampicillin or indinavir. However, these were noted to have been seen in acidic urine instead of alkaline. Looking at the patient’s medication list, ciprofloxacin was noted which can also precipitate as crystals in alkaline urine after administration.
