My father Creatinine(serum) is 1.3mg/dl

Dear Patient: Creatinine is the metabolic product of muscle. It can be produced by the muscles of our body, and it can also be gotten from the meat we take. Creatinine in our blood will be excreted out by our kidneys, and the creatinine level of our blood changes in a stable range. The normal range of creatinine level in man is 0.7~1.2mg/dL, and the normal range of creatinine level in woman is 0.5~1.0mg/dl.
As i said, creatinine is the product of muscle, and for patient who have creatinine level 1.3, his high creatinine level may be caused by many reasons. For example, creatinine level will rise if people just take much meat, and they will also have high creatinine if they just have taken strenuous exercise. While in this cases, patient’s high creatinine level will not stay for a long time, so patient do not need to worry in this condition

Hope this helps.
Take Care
