I have gone through lft. My total protein level is 8.1 and sgpt is 40. In usg shows left kidney has minimal fullness of pelvicalyceal system. Need adv

Multiple. Sgpt of 40 appears to be normal by our lab cut offs. Total protein of 8.1 is normal or minimally elevated, so your liver seems ok by these tests. Left kidney minimal fullness - that by itself doesn't tell me what the problem is and where it is located.
