Question: Are the creatinine levels in a healthy 30 year old woman much different from a 6 year old girl?
I just wanted to know if there was a big difference in the levels. What the level of a healthy woman, and the level of a healthy child? Dr. Joshua Rassen responds:
Creatine is used by the body for muscle contraction. Actually it is not measured as a routine laboratory test to my knowledge. (You can get measurements of creatine kinase or creatine phosphokinase, which are actually something different from creatine.) Actually I wonder if you are asking about creatinine. Creatinine is produced when creatine is broken down. Creatinine is measured quite often as it is a very useful test to check how the kidneys are working. In a healthy person, the creatinine level depends on the amount of muscle that a person has. So the level of a 30 year old woman should be higher than a 6-year old girl. Here is a table of normal values: · Adult female: 0.5-1.1 milligrams per deciliter (mg/dL) · Adult male: 0.6-1.2 mg/dL · Adolescent: 0.5-1.0 mg/dL · Child: 0.3-0.7 mg/dL · Infant: 0.2-0.4 mg/dL · Newborn: 0.3-1.2 mg/dL. You can see that normal values are actually a range. The normal values for a child are 0.3 to 0.7 while an adult woman is generally between 0.5 and 1.1. I hope this information is what you are seeking. Thank you for your question. Dr. Johsua Rassen -- Joshua Rassen, MD, is a board-certified internist and geriatrician in northern California. He has a private practice in geriatrics and internal medicine and is the Chief of the Division of General Internal Medicine at California Pacific Medical Center.
