What does creatinine level 2.5 mean? When a person goes to have a physical 
examination, he or she is told to have high creatinine level 2.5. What is 
creatinine? What is the normal range of creatinine? What does creatinine level 
2.5 mean? What measures should we take to decrease the creatinine level 2.5?
Creatine is a nitrogenous organic acid that occurs naturally in vertebrates 
and helps to supply energy to all cells in the body, primarily muscle. Creatine 
is naturally produced in the human body from amino acids primarily in the kidney 
and liver. It is transported in the blood for use by muscles. Approximately 95% 
of the human body's total creatine is located in skeletal muscle. after 
metabolism, creatinine will come to kidney for filtration. When the kidney is 
damaged, the ability of discharging creatinine will also decrease.
What is the normal range of creatinine (High Creatinine Levels )? Different labs have different 
standards. Generally, the normal range is 0.53 to 1.1. What does creatinine 
level 2.5 mean? Firstly, we should explain the specific ones according to the 
different stages.
Stage 1 GFR ≥90 mL/min/1.73m2 creatinine normal
Stage 2 GFR 60-89 mL/min/1.73m2 creatinine 133-177μmol/L (1.6-2.0mg/dL)
Stage 3 GFR 30-59 mL/min/1.73m2 creatinine 186-142μmol/L (2.1-5.0mg/dL)
Stage 4 GFR 15-29 mL/min/1.73m2 creatinine 451-707μmol/L (5.1-7.9mg/dL)
Stage 5 GFR <15 mL/min/1.73m2 creatinine 451-707μmol/L (5.1-7.9mg/dL)
From the above, we can find out that creatinine 2.5 mean that patients have 
come into stage 3 of chronic kidney disease. In this stage, chronic kidney 
disease patients may have the following symptoms such as fatigue, too much fluid 
in the body or edema, back in pain, sleeping problem, hematuria(Hematuria and Kidney Disease), proteinuria (Proteinuria and Kidney Disease), 
and so on.
What should chronic kidney disease patients do to prevent from such high 
creatinine?
In western countries, hormones and immunosuppressive agent is applied. After 
applying for a long time, chronic kidney disease patients will find out that 
they can only stop the symptoms for the time being and can not treat chronic 
kidney disease from root. In the research of the kidney disease causes, we find 
out that most or 95% of kidney disease is caused by the disorder of immune Immunotherapy. So we created a new immunotherapy.
