It is not mandatory to have protein before having a transplant with high nk cells. Whether to play protein depends on whether the patient has hypoproteinemia, and whether the patient to do the transplant is not directly related. Hypoproteinemia patients can lead to generalized swelling, multiple plasma cavities, and can even lead to thrombosis, heart failure and other occurrences, and need to actively correct the proteinemia. Correction of hypoproteinemia is often through the transfusion of albumin, but also rich in high-quality protein diet to increase protein supplementation. For patients with hypoproteinemia, improving the hypoproteinemia is one aspect, and the other aspect is to find the cause of the hypoproteinemia and remove the cause in order to fundamentally improve the hypoproteinemia.
