shortly what is Creatinen

**Creatine**

 is a molecule produced naturally in the liver, pancreas, and kidneys. People also consume creatine in their diets, mostly from meat. 
Creatine is distributed throughout the body, but about 95% is found in skeletal muscles. Once creatine reaches the muscles, it exerts several effects responsible for the improvement of muscle function and energy metabolism. 
Creatinine is removed from the blood chiefly by the kidneys. Serum creatinine is the most commonly used indicator (but not direct measure) of renal function.

Shortly what is HbA1C

HbA1c Test for Diabetes:

HbA1c (glycated haemoglobin, haemoglobin A1c) occurs when haemoglobin, the oxygen-carrying protein in red blood cells, becomes bonded with glucose in the bloodstream. The bonding with glucose is called glycation.

The higher a person’s blood glucose levels have been, the higher the number of red blood cells that will have become glycated, and therefore the higher HbA1c level they will have.

Note that red blood cells exist in the body for around 3 months, therefore an HbA1c levels generally reflects a person’s blood glucose levels over the previous 3 months.

The haemoglobin A1c test gives an indication of how well your "diabetes" is controlled. Together with the fasting plasma glucose test, the HbA1c test is one of the main ways in which type 2 diabetes is diagnosed.
