On my last laboratory, I asked to have a creatinine. Though it was not part of my doctor’s order i still wanted to check it out. For those of you who don’t know creatinine is a blood test that is used to gauge if your kidneys are functioning well. So I got a little paranoid when I saw that my crea is below the normal level. I researched a little and here is what i found out.
Normal levels of creatinine in the blood are approximately 0.6 to 1.2 milligrams (mg) per deciliter (dl) in adult males and 0.5 to 1.1 milligrams per deciliter in adult females. (In the metric system, a milligram is a unit of weight equal to one-thousandth of a gram, and a deciliter is a unit of volume equal to one-tenth of a liter.)
Muscular young or middle-aged adults may have more creatinine in their blood than the norm for the general population. Elderly persons, on the other hand, may have less creatinine in their blood than the norm. Infants have normal levels of about 0.2 or more, depending on their muscle development. In people with malnutrition, severe weight loss, and long standing illnesses the muscle mass tends to diminish over time and, therefore, their creatinine level may be lower than expected for their age.
A person with only one kidney may have a normal level of about 1.8 or 1.9. Creatinine levels that reach 2.0 or more in babies and 10.0 or more in adults may indicate severe kidney impairment and the need for a dialysis machine to remove wastes from the blood. source : Medicinenet.com
Because of this I realized that there is nothing to worry about since my crea is lower than normal (which also was confirmed by my doctor). I should be alarmed if my crea is higher because that is the time that I am in deep trouble which I am keeping my fingers crossed won’t happen.
