                                For adults, a blood phosphate level above 4.5 mg/dL is officially diagnosed as hyperphosphatemia. This condition, which indicates an abnormally high concentration of phosphate in the blood, can have serious health consequences, particularly for individuals with kidney disease. Understanding what is considered high phosphate is the first step toward effective management and prevention of complications.
