What does a high bun and creatinine reading indicate?

What does a high bun and creatinine reading indicate?

Co-tango usually: The BUN is usually 10 times the creatinine. When the creatinine goes up, the BUN goes up similarly to roughly keep this proportion, in most kidney disease states. The notable exception is when the creatinine goes up say by 20% to 1.2, but the BUN goes up *5 to 50. This strongly suggests a pre-renal state, commonly dehydration. Mild elevations of BUN with normal creatinines aren't of concern. ...Read more

My creatinine reading was 138, can it be 100% treatable ? Or reduced ?

My creatinine reading was 138, can it be 100% treatable ? Or reduced ?

Depends: Serum creatinine of 138 mol/L is equivalent to 1.56 mg/dl. I agree that your renal function is abnormal. However, whether it is treatable depends on the etiology of renal dysfunction. ...Read more

What are the causes of high reading of creatinine in the urine [not blood]?

What are the causes of high reading of creatinine in the urine [not blood]?

A lot of factors: Your kidney function and its filtration rate, what you eat, age, the amount of your muscle mass, liver function, the rate of cell breakdown in your body (catabolism) are some factors that will influence how much creatinine you pee out in the urine. ...Read more

What does a high bun/creatinine ratio reading mean?

What does a high bun/creatinine ratio reading mean?

See below: An elevated BUN with normal creatinine and a ratio of [generally more than 18-20] occurs most commonly in dehydrated individuals and is not a sign of kidney damage.It may also occur in in certain other conditions like bleeding in the intestines, artificial nutrition intravenously of Amino Acids and use of steroids. ...Read more

On a metabolic workup, what does a low bun/creatinine ratio reading mean?

Maybe, kidney diseas: In prior answers, explained bun, creatinine, normal ratio, and high ratio. Low ratio means that the BUN is likely low or normal with relation to the creatinine, indicating that there is adequate blood or volume flowing to the kidneys, but the kidneys are impaired or disease in some way. Need a nephrologist - kidney specialist. ...Read more

During a metabolic workup, what does a high bun/creatinine ratio reading mean?

Decrease in flow.: Bun=blood urea nitrogen, byproduct of proteins ingested, if rise to high levels due to kidney problem, can cause toxic affects on the body. Creatinine= measurement of renal function. Normal bun/cr ratio about 10. The higher that ratio, the more likely it is not intrinsic kidney disease per se, but reduction in blood flow or volume to kidney, like when on strong diuretic-prerenal-reversible. ...Read more

Hi sir my mothers serum creatinine lab reading is 3.1, is it causesany heavy problem to the kidneys?

Renal Insufficiency: Discuss this with her and pcp. This is consistent with renal insufficiency or early renal failure. If pcp is comfortable managing this, is not a problem as long as your mom follow instructions and take medications (i.e. For blood pressure) as indicated and avoid things like high protein in diet. Other conditions (i.e. Diabetes) should be well controlled. She can progress but hard to predict. ...Read more

How to reduce serum creatinine and blood urea level for 62 yr old male right now the readings are: serum creatinine ---> 2.1 blood urea --->67?

High creatinine: You need to see a nephroloigist (n) for a history, physical examination and lab studies. You need a 24 hour urine for creatinine clearance and protein determination. You also need more blood work and a renal ultrasound to see the size and morphology of your kidneys. If you have some obstruction of your urinary tract, lowering of you elevated levels may be possible. See a n for more infoirmation. ...Read more

Hi, why should exercising cause a trace amount of blood in urine test? also if orange juice, coffee, and cola is drank within 3 or 4 hrs of urine test at Physician's office can that give false creatinine and albumin readings?

Hi, why should exercising cause a trace amount of blood in urine test?  also if orange juice, coffee, and cola is drank within 3 or 4 hrs of urine test at Physician's office can that give false creatinine and albumin readings?

Myoglobin: Working out hard releases a little myoglobin into your bloodstream and thence the urine, and pounding the pavement can wreck some red cells and their contents leaks into the urine. There is no "false" creatinine urine assay; it's a normal component that varies with your muscle mass. It won't give false albuminuria. The most common cause of protein in the urine is orthostatic proteinuria, harmless ...Read more
