Creatinine is a supernatural matter that is competent of maintaining human bodies younger, stronger and supple. Creatinine is a naturally happening amino acid that has been proved to fabricate strength in humans. Creatinine is formed from creatine, a molecule of key significance for energy production in muscles. The substance creatine is produced from muscle metabolism, when food is transformed into energy. Creatinine is a nitrogenous waste molecule produced by muscular activity. Creatinine is made at a steady rate and is not affected by diet or by normal physical activities. Creatine is broken down into another substance called creatinine, which is taken out of the blood by the kidneys and then passed out of the body in urine. Roughly, about 2% of the body's creatine is transformed to creatinine daily. Creatinine is conveyed to the kidneys, through the bloodstream. The kidneys filter out most of the creatinine and dispose of it in the urine. Since the muscle mass in the body is comparatively constant everyday, the creatinine level in the blood usually remains fundamentally unaffected each and every day. Creatinine and creatinine clearance tests calculates the level of the waste product creatinine in the blood and urine. These tests portray how well the kidneys are functioning. If the kidneys are damaged and cannot work normally, the amount of creatinine in the urine goes down, though its level in the blood goes up.

Is it imperative to ensure blood creatinine levels?

Yes. It is very important to ensure blood creatinine levels. The kidneys uphold the blood creatinine in a normal range. Creatinine has been found to be quite consistent pointer of kidney function. If the kidneys become damaged for any reason, the creatinine level in the blood will mount up due to poor elimination by the kidneys. Hence, abnormally high levels of creatinine caution the likely break down or failure of the kidneys. So, it is vital to take normal blood tests habitually to ensure the amount of creatinine in the blood. A more accurate measure of the kidney function can be determined by manipulating how much creatinine is cleared from the body by the kidneys and it is referred to ‘creatinine clearance’.

What are the causes for high blood creatinine?

•  Any condition that damages the function of the kidneys will almost certainly raise the creatinine level in the blood. It is essential to identify whether the process leading to kidney dysfunction (kidney failure, azotemia) is very old or new. The most common reasons of very old kidney disease in adults are high blood pressure and diabetes mellitus. Specific medicines can at times cause unusually high creatinine levels.
•  According to Medline Plus, a website of the National Institutes of Health, the fleeting increases in creatinine can be caused by dehydration, the lack of moisture. Patients with one kidney such as transplant recipients or kidney donors seem to be particularly susceptible to the effect of dehydration on creatinine. It is essential to exclude dehydration as a likely cause of high creatinine in this population, as patients may incorrectly think that their remaining kidney is also deteriorating.
•  An elevated creatinine level has been associated to atherosclerosis, or hardening of the arteries. Fleeting high levels of creatinine can also be due to the diverse types of heart surgery, such as aneurysm repair or stent insertion. It is vital to eliminate these reasons when assessing high creatinine levels.
•  Serum creatinine can also rapidly increase after swallowing of huge amount of dietary meat.

What are the symptoms of high creatinine levels?

The symptoms of kidney dysfunction differ broadly. A few people may have an accidental finding of brutal kidney disease and high creatinine on routine blood work without having any symptoms at all. For few others, depending on the cause of problem, a lot of dissimilar symptoms may be present including:

•  Dehydrated sensation.
•  Fatigue
•  Shortness of breath.
•  Bewilderment or disoriented
•  Headache
•  Loss of appetite
•  Weight changes
•  Low-grade fever
•  Weariness or a widespread sense of depression.
•  Specific symptoms are: Decreased output of urine, where urine may appear dark in color, edema or puffiness such as in the face and around the eyes or other areas and pain in the lower back or lumbar area.

What are the various types of creatinine tests?

There are 3 types of creatinine tests that are done. They are:

• Creatinine clearance test: A creatinine clearance test calculates how well creatinine is eliminated from the blood by the kidneys. A creatinine clearance test offers better details than a blood creatinine test on how well a perosn’s kidneys are functioning. A creatinine clearance test is perfomed on both a blood sample and on a sample of urine collected over 24 hours (24-hour urine sample).
• Blood creatinine level: The blood creatinine level depicts how well the kidneys are funtioning. A high creatinine level may indicate that the kidneys are not functioning appropriately. The quantity of creatinine in the blood relies partially on the quantity of muscle tissue a person have. Usually, men have higher creatinine levels than women.
• Blood urea nitrogen-to-creatinine ratio (BUN:creatinine): The levels of blood creatinine and blood urea nitrogen (BUN) can be utilized to predict the BUN-to-creatinine ratio. A BUN-to-creatinine ratio can aid the doctor to ensure for problems, such as dehydration, that may cause irregular BUN and creatinine levels. Urea is a waste product made when protein is broken down in your body. Urea is produced in the liver and eliminated from body in the urine. A blood urea nitrogen (BUN) test computes the amount of urea in a person’s blood. Similar to creatinine, it can assist the doctor to see how well the kidneys are functioning.

What are the Normal creatinine levels?

•  Normal creatinine levels in the blood are just about 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.
•  Infants have normal levels of about 0.2 or more, depending on their muscle growth.
•  Well-built young or middle-aged adults may have more creatinine in their blood than the normal.
•  Conversely, aged people may have less creatinine in their blood than the normal.
•  In people with malnutrition, severe weight loss, and very old sicknesses, the muscle mass may reduce eventually and, hence, their creatinine level may be lower than expected for their age.
•  An individual with only one kidney may have a normal level of about 1.8 or 1.9.

What are the high Creatinine levels and what do they indicate?

Creatinine levels that reach 2.0 or more in infants and 10.0 or more in adults may point out brutal kidney damage and the necessitate for a dialysis machine to get rid of wastes from the blood. Often, elevated levels of creatinine indicate unswervingly to the body's filtration system and how that system is working. The major worry is a decrease in kidney function. High levels also indicate:

• Injure to or inflammation of blood vessels in the kidneys (glomerulonephritis)
•  Bacterial infection of the kidneys (pyelonephritis)
•  Decease of cells in the kidneys small tubes (acute tubular necrosis)
•  Prostate disease, kidney stone, or other causes of urinary tract impediment.
•  Abridged blood flow to the kidney due to shock, dehydration, congestive heart failure, atherosclerosis, or complications of diabetes.
