Generally speaking, the normal reference value of alkaline phosphatase is 45-125 U/L. Alkaline phosphatase 32 U/L is slightly low, which generally does not affect health. Low alkaline phosphatase is commonly seen in several situations. The first is malnutrition, where patients should have a balanced diet with appropriate amounts of vitamins, protein, fiber and other nutrients. The second is anemia, which can be adjusted by diet. Anemia caused by excessive blood loss should be treated with active hemostasis and, if necessary, blood volume expansion; for hemolytic diseases, the primary disease should be treated and component transfusions should be administered. The third type is vitamin deficiency, such patients should eat more fresh fruits and vegetables or take multivitamins for treatment. Another possible cause of low alkaline phosphatase is severe chronic nephritis, childhood thyroid insufficiency, celiac disease, cachexia, hereditary hypophosphatemia, and severe viral infections. In addition, when a pregnant woman has hepatitis, alkaline phosphatase is also reduced. Therefore, when alkaline phosphatase is 32 U/L, you need to go to a regular hospital promptly to determine the specific cause of low alkaline phosphatase through other related tests, combined with clinical symptoms, etc. to avoid delaying the disease.
