My son age 4 got slightly high phosphorus in blood test while calcium and vitamin d were normal. It was a part of his routine tests. Phosphorus 6.2( Range- 3.1-6.0) Calcium 9.9 ( 8.8-10.8) Vitamin D 50 ( Range 30-100). He was taking vitamin d sachets ( 1/ week last month and took 1 sachet this month) Besides meconerv and a to z syrup on the recommendation of a pediatrician who said it's good to take but no tests were done at that time. Does this pose any problems?
