There is no specific number in the creatinine level analysis that suggests the patient needs to undergo dialysis, but this decision is made based on many factors, as follows:

• Results of other kidney function tests such as blood urea nitrogen, potassium levels, and fluid retention.
• The severity of the patient’s symptoms.
• The patient’s age.
• The general health of the patient.
• The patient’s ability to make some changes in his lifestyle to adhere to the scheduled dates for dialysis.

A creatinine analysis helps to calculate the estimated glomerular filtration rate for renal function, but does not fully predict what symptoms a patient will experience.

According to published research to measure blood creatinine and urea levels before and after a group of patients of different ages were subjected, most patients had high levels of creatinine in the blood ranging between 7.6-15 mg/dL, and dialysis reduced these levels, but the final decision rests with the patient’s submission For this procedure to the doctor’s assessment of his condition based on the above.
