I’d like to also extend my welcome to the Connect community along with @rosemarya. My recent history of a bone marrow transplant has me up close and personal with blood numbers.
The results you’ve posted for being 61 really don’t look that far out of whack. To this day my creatinine and Alkaline Phos are about the same level as yours. My doctors have very little concern over that at this point and I’m 67.
Your ferritin number appears in the normal range. That basically shows the amount of iron in your blood.
The eGFR is the flow rate of your urine through your kidneys. At your age, in a perfect world charts would want that at >60. Your number is 50 so that’s pretty flow-worthy. Just up your water intake to keep things flowing. Mine is around 42 right now because of some meds I’m taking.

My husband at 70 has a creatinine which has run from 1.1 to 1.2 for 10 years. It’s consistent and stable. With annual physicals his doctor feels he is in excellent health with no concern for that creatinine number. Doctors take into account the overall physical shape of a person as well as just one number.

Rosemary is so right that blood tests are more of a piece of the larger puzzle. There are more clues needed before you’ll get a definite answer.
Since your kidney numbers appear to be pretty normal, you feel your doctor is concentrating on your liver? What led him to the follow up?
Lab results which would be more value in showing liver damage or involvement would be a liver enzyme panel:
ALT alanine aminotransferase
AST (aspartate aminotransferase.
Bilirubin
Do you remember seeing these numbers on your CBC panel?
