Is a 2 creatinine level dangerous?

Need follow-up now!: It is not dangerous now but it indicates impaired renal function that may become dangerous. See your doctor asap and see this site for info. http://www.mayoclinic.com/health/creatinine/my00144/dsection=results.

Interpretation: Serum creatinine is affected by protein intake, gender, age, race, muscular build, and renal function. A rising creatinine is always of concern. "normal" on lab tests is generally less than 1.2 mg/dl. Renal function can be estimated with a more complex formula or measured with a 24 h urine collection.
