Does high bun creatinine mean kidney cancer? My 10 year old son has it

Does high bun creatinine mean kidney cancer? My 10 year old son has it

Usually not: There are many other more common reasons for a child to have a higher than normal bun/creatinine other than kidney cancer. Some of these include: dehydration, medications, infections, and urinary tract abnormalities. It is important to find out the cause of the impaired kidney function so that it can be treated. ...Read more

Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

31 white female, 1.2 creatinine level, normal BUN, 82 Prolaction level, 56 GFR should I be concerned?

31 white female, 1.2 creatinine level, normal BUN, 82 Prolaction level, 56 GFR should I be concerned?

Prolactin and kidney: Hi. Those are two unrelated conditions. Serum prolactin (PRL) can accumulate in chronic kidney disease (CKD), but your CKD is way too mild to cause that. Ergo, you have hyperprolactinemia. Do you have amenorrhea and galactorrhea? If not, the PRL may be a red herring, and macroprolactinemia should be tested for. Why you fall into the category of Stage 4 CKD is unknown to us. So, eval. PRL and CKD ...Read more

Would losing 12 pounds on an already petite woman and dramatically decreasing protein cause BUN creatinine level to drop from 15 to 6 in 3 months?

Would losing 12 pounds on an already petite woman and dramatically decreasing protein cause BUN creatinine level to drop from 15 to 6 in 3 months?

Loss of muscle mass: In addition to losing fat, you are losing muscle mass and that is reflected in the drop in creatinine. You may wish to increase your protein intake and exercise.
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. Drink enough water daily so that your urine is mostly colorless.
Practice safe sex. ...Read more

I recently had a blood test. The BUN was 10 and creatinine was 1.2. I am a 36 year old male, Asian and am worried about the high creatinine levels?

I recently had a blood test. The BUN was 10 and creatinine was 1.2. I am a 36 year old male, Asian and am worried about the high creatinine levels?

Need more info: Creatinine level in blood depends on the kidney function, but also on the amount of protein intake and muscle mass and activity that you have.
You need a glomerular filtration test for a better evaluation of your kidney function. ...Read more

Husbands blood creatinine level is 1.18, reference range is (0.50-1.20 mg/dl). Bun/cre ratio is 11.0, range is (10-20). Is there anything to be concerned about here?

Husbands blood creatinine level is 1.18, reference range is (0.50-1.20 mg/dl). Bun/cre ratio is 11.0, range is (10-20). Is there anything to be concerned about here?

No Need to Worry: Blood creatinine and bun/cre ratio are measures of kidney function and fluid balance in the body. These numbers are well within range of normal. Of course you should speak with your physician if you have concerns. Clinical correlation to any disorders is the key. If your husband is well, then there is no need to worry. The kidneys are working fine. ...Read more

Having a 1.5 creatinine level, BUN is 17, should I be concern?

Monitor for now: Normal levels for females range from 0.5 - 1.1. However, as we get older, our kidney function does decline and creatinine levels increase. Dehydration and certain medications/procedures may also cause a bump in creatinine levels. I'd recommend a medication review and follow up labs in 1-3 months to monitor your creatinine levels, unless you notice changes in your urine in the interim. ...Read more

What does it mean low creatinine levels and high bun creatinine ratio?

Muscle mass: Serum levels of creatinine depend on renal function, muscle mass and intake of muscles foods. A low creatinine level is of no consequence as long as you are not emaciated. Paralyzed, or have extensive amputations. High ratio just reflects low creatinine. ...Read more

I have Creatinine level of 1.2, normal BUN, GFR of 56, I'm 31, prolacton level of 82. Any suggestions?

Um, those are: Not necessarily abnormal. Prolactin has more significance if it is sky high (it isn't). The others at most would probalby indicate a bit of dehydration. ...Read more

What does it mean if your creatinine level is too high 1.16 and your bun/creatinine ratio is very low at a 5?

What does it mean if your creatinine level is too high 1.16 and your bun/creatinine ratio is very low at a 5?

Why do you ask?: Labs mean nothing in the absence of a clinical history. You might be a vegan bodybuilder. When I was lifting weights every day, my creatinine ran 1.6-1.8. The fellow-pathologists with whom I've discussed it think that reports generated by labs are causing overdiagnosis of renal disease (it's subscience -- "there's an adjustment for race because black people are more muscular.") ...Read more

What is a bun/creatinine ratio? How is it calculated and if mine is 22 but my other levels are fine what should I do?

What are the actual: Numbers? BUN number divided by creatinine number. Normal range is 10-20. 22 may not be abnormal if individual levels of BUN and creatinine are normal. Discuss the numbers with your doctor at the next visit. ...Read more

Tests, tests, tests: Tests results always have to be interpreted in a context. When they measure the temperature of the winner of the Boston Marathon 2 yrs ago it was over106 F. Was he very ill? NO! He had been using his bodies muscles at full output for over 2 hrs straight. The heat generated raised his body temp a lot and he soon cooled off.

Why is bun, creatinine, and electrolyte levels ordered on someone with ards?

Sick patient: When a patient has ards, thje patient is very sick. Thus other organs can get damaged including the kidney. BUN and creatinine are makers of kidney injury and your doctors are going to monitor its function routinely. The electrolytes are also changing and need to be corrected routinely. ...Read more

Which etiology results in an elevated bun level with a normal serum creatinine level?

Which etiology results in an elevated bun level with a normal serum creatinine level?

Multiple causes: BUN is a breakdown of ingested protein, but becomes elevated compared to creatine, in cases of increased catabolism (breakdown). Such things as a high protein diet, use of some steroids, some infections, or volume depletion may commonly raise BUN levels. In a hospital setting, tube feeding, tpn, GI bleeding, infections, decreased flow to the kidneys, and use of steroids are frequent contributors. ...Read more

My urine creatinine was 20 when 4 months ago it was 73, my BUN level was 7. What could be causing this?

This means nothing: Urine creatinine varies with your hydration. You excrete a certain amount daily depending mostly on your muscle mass. Drink twice as much water, and you cut your creatinine in half. It's worth measuring only as a standard against which to compare other elements measured in your urine. A "low BUN" means nothing. You're not a kidney patient. I'm sorry no one explained this to you. ...Read more

My creatinine levels were flagged at 1.18 my bun was normal at 11 and my eGFR was 68 normal for African American I am 37?

You're fine: As a pathologist, I join many of my friends in nephrology in thinking that these "estimated GFR's" are subscientific stuff driven by non-evidenced based factors. The racial stuff was actually introduced "because black people are more muscular." When I was lifting wieghts daily, my creatinine ran 1.6-1.7. You're not a kidney patient in my humble opinion. ...Read more

My creatinine level and bun are normal. My GFR is lower than last year (50). I am caucasian. Should I be concerned about kidney function? Thanks.

Low GFR: GFR below 60 for > 3 months may be an indication of chronic kidney disease. As cardiovascular factors (blood pressure, glucose, lipids) are a major cause of kidney disease, these should be controlled. GFR also reduces with age. ...Read more

Dehydration: Were you dehydrated when the blood was drawn. If you were asked to come fasting, you may not have taken enough water. Dehydration affects BUN more than it affects creatinine. Since creatinine is normal, I would not worry about BUN.
At your next test, make sure you drink water in the morning before the blood is drawn. ...Read more
