Bu dönüştürücü ne yapar?
Bu araç, kreatinin değerlerini µmol/L, mmol/L, mg/dL, mg/100mL, mg%, mg/L ve µg/mL arasında dönüştürür. Bir laboratuvar raporunda kreatinin mg/L cinsinden gösterildiğinde ve µmol/L, mmol/L veya mg/dL cinsinden eşdeğer değere ihtiyacınız olduğunda faydalıdır. Dönüştürme kreatinine özgüdür ve üre, BUN (kan üre azotu), sistatin C veya diğer böbrek markörleri için kullanılmamalıdır.

How to Convert Creatinine Units
For creatinine, 1 mg/dL is equivalent to 88.4 µmol/L. To convert mg/dL to µmol/L, multiply by 88.4. To convert µmol/L to mg/dL, divide by 88.4.
When creatinine is reported in mg/L, multiply by 8.84 to obtain µmol/L. Conversely, divide µmol/L by 8.84 to obtain mg/L.
Equivalent Creatinine Reporting Units
- mg/dL, mg/100mL, and mg% represent the same numerical concentration.
- mg/L and µg/mL are numerically equivalent.
- 1 mmol/L equals 1000 µmol/L.
- 10 mg/L equals 1 mg/dL and approximately 88.4 µmol/L.
Clinical Context and Limitations
Creatinine is a waste product associated with normal muscle metabolism and is commonly used as a filtration marker. Serum creatinine is frequently incorporated into equations that estimate glomerular filtration rate, but the concentration alone does not provide a complete assessment of kidney function.
Interpretation should consider the specimen type, laboratory method, local reference interval, and the patient’s clinical context.
- Creatinine concentration may be influenced by muscle mass, age, diet, hydration, pregnancy, medications, and acute illness.
- A creatinine result should not be converted directly into an eGFR without using a validated equation and the required patient variables.
- Kidney assessment commonly combines serum creatinine-based eGFR with urine albumin measurement when clinically appropriate.
- Reference intervals for serum creatinine must not be applied to urine creatinine results.
