Yes, ideally one should stop taking vitamin D before a blood test.
No, they cannot detect lack of vitamins.
Adding more iron and B12 helps increase MCH values. Consuming vitamin C and fiber, along with foods that contain iron, may also help increase the MCH levels.
No, it is not possible.
After an injection the serum B12 value rises quickly to far above the upper reference value on average 150-700 pmol/L
