The identification of the crystals depicted in this image are triple phosphate crystals. Triple phosphate crystals may be normal but are usually associated with alkaline urine. These colorless crystals have a characteristic
"coffin lid" appearance.

What is the identification of these crystals seen in urine with an alkaline pH?

Intravascular hemolysis is typically associated with increased levels of serum (plasma) LDH and bilirubin, and an increased number of reticulocytes. Serum LDH is found in higher levels during intravascular hemolysis due to fact that high levels of LDH are normally found within the red cells, but is now being spilled into the bloodstream via red cell lysis. Bilirubin is a breakdown product of hemoglobin, which has also been spilled into the bloodstream from broken red blood cells via hemolysis. Reticulocytosis is a reflection of the release of an increased number of immature red blood cells from the marrow to account for the red blood cells that are lost through hemolysis. This is a normal response. Failure to show an increased reticulocyte count with hemolytic episodes or hemorrhage would indicate an ineffective erythropoiesis (possible bone marrow function problem).
Which of these blood levels will increase during intravascular hemolysis?
