What is creatinine?
Creatinine is a chemical waste molecule that is generated from muscle metabolism. Creatinine is produced from creatine, a molecule of major importance for energy production in muscles. Approximately 2% of the body's creatine is converted to creatinine every day. Creatinine is transported through the bloodstream to the kidneys. The kidneys filter out most of the creatinine and dispose of it in the urine.
Because the muscle mass in the body is relatively constant from day to day, the creatinine level in the blood normally remains essentially unchanged on a daily basis.
Why is it important to check blood creatinine levels?
The kidneys maintain the blood creatinine in a normal range. Creatinine has been found to be a fairly reliable indicator of kidney function.
As the kidneys become impaired for any reason, the creatinine level in the blood will rise due to poor clearance by the kidneys. Abnormally high levels of creatinine thus warn of possible malfunction or failure of the kidneys. It is for this reason that standard blood tests routinely check the amount of creatinine in the blood. A more precise measure of the kidney function can be estimated by calculating how much creatinine is cleared from the body by the kidneys and it is referred to creatinine clearance.
What are "normal" blood creatinine levels?
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 <a href="/script/main/art.asp?articlekey=88521">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.
FATHER, I COME PRAYING FOR SIJU AND ASKING HIS BODY TO MANUFACTURE THE AMINO ACIDS IT NEEDS TO AID IN FILTERING THE BLOOD IN THE KIDNEYS. LET THE KIDNEYS BEGAN TO FUNCTION AS YOU DESIGNED THEM AND ALLOW THIS WAM, SIJU, MY BROTHER, TO BE A WITNESS OF YOUR MIRACLEOUS HEALING POWER IN THE BODY OF ALL MANKIND. YOU HEAL UF OF ALL OUR SINS, PLEASE HEAL HIM OF ALL HIS PHYSICAL INFIRMITIES, IN THE NAME OF JESUS, I ASK FOR SIJU, AMEN.
