You are normal: Creatinine levels are a reflection of muscle mass and kidney function. Bad kidney function never results in low creatinine. If you are skinny and do not eat much meat, your creatinine may be lower than "normal" but it is not abnormal at all. There is no need to try to increase your creatinine. ...Read more

My serum creatinine is 4.0 what it means?

High creatinine: Before I can answer your question, I need to know your height and weight. If you are a tall person with a large amount of muscle mass, it is less serious than if you have less muscle mass. See a nephrologist to take a history to see if you have high BP or diabetes. You also need a renal ultrasound and a 24 hour urine collection to assess your renal function and to see if you have proteinuria. ...Read more

What does it mean if my BUN is 22, BUN Creatinine 26 and creatinine serum is 0.86? I am a 54 yr old woman

Drink water: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your creatinine is normal. Your BUN is slightly elevated and may be because you were fasting when the blood was drawn and were dehydrated from not drinking water.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex. ...Read more

Hi, my son 6 years old, when healthy, had bloods done, results were low ferritin, low lymphocytes 1.8, low wbcs 4.6 and low serum creatinine.

Not to worry: All of these things, with the exception of the low ferritin, are fine. The low creatinine means his kidneys work uber-great! . The WBC likely reflects mild suppression from a recent viral illness. The low ferritin is very common, indicating he needs more iron in his diet or a supplement. Please do not get in the habit of focusing on lab numbers when your child is healthy. He is healthy - enjoy! ...Read more

5yr girl with 7 past urine tests in row show trace blood in it, no u.T.I.! so checked serum creatinine an it's ok but cbc, iron on low side, . Any clue?

5yr girl with 7 past urine tests in row show trace blood in it, no u.T.I.! so checked serum creatinine an it's ok but cbc, iron on low side, . Any clue?

? urine Ca/cr ratio: Sometimes this is a sampling issue, and a squat and pee sample is often a vaginal wash out with all sorts of things in it. If it is a good clean catch specimine I would wonder where the blood is coming from. Small amounts can accompany excess calcium loss through the kidney tubules. A spot check of the urine ca/cr can pick this up, usually some protein in the pee along with it. Talk with your doc. ...Read more

My lab reports are serum creatinine 80, GFR 72, and creatinine clearance 69.9. my 24 hr urine creatinine was 6.9 and spot urine 2.2. What does it mean?

Not much: You're 55 years old and -- congratulations -- a recovered problem drinker. Unless you're especially fit or heavily-muscled, your creatinine may be a bit high and maybe your kidneys are getting old -- but this level is perfectly compatible with good health and if you had serious kidney disease, it would be a lot worse by now. Eat sensibly, stay fit and I bet your kidneys will last a lifetime. ...Read more

What is a regular serum creatinine level?

0.6 to 1.4 mg/dL: Creatinine is a product of muscle metabolism. Because women generally have less muscle mass than men, their values are lower. Because of increased volume during pregnancy, lower limits of normal may be 0.4 -0.5 mg/dl. As an individual ages, the muscle mass may decline therefore the serum creatinine values may not adequately reflect the underlying renal function. ...Read more
