Testosterone and creatinine clearance?

Testosterone and creatinine clearance?

Clarify: I'm not sure what your question is. Testosterone should be used with caution in patients with conditions involving edema, such as impaired kidney function, as the hormone may worsen edema. One of the adverse effects of testosterone is an increase in serum creatinine concentration. ...Read more

Creatinine Clearance (Definition)

Creatinine clearance is used in clinical practice to give an estimate of overall kidney function, or glomerular filtration rate. Generally normal is considered 100 or above, but it goes down every year and elderly patients may have low clearance ...Read more

What is difference of creatinine serum VERSUS creatine kinas total serum?

Different tests: Creatinine is a waste product of (mainly muscle) metabolism, & builds up when the body (kidney) cannot get rid of it. Creatine Phosphokinase, AKA Total CPK, is an enzyme produced by certain cells in the body that produces creatine byproducts (muscle, bone, brain, heart have CPK). An elevated CPK means one of these organs is/was damaged in some way. So the 2 tests measure different things. ...Read more

Creatinine clearance? What for?

Kidney function: Creatinine clearance is a calculation that serves as a measure of kidney function. There are 5 stages of kidney disease before end-stage. The stage guides treatment and allows the doctor to monitor changes over time. ...Read more

What is a creatinine clearance rate and GFR?

What is a creatinine clearance rate and GFR?

CrCl & GFR: GFR stands for Glomerular Filtration Rate which is a measure of the filtering function of your kidneys. Creatinine Clearance is one of the methods used to measure a person's GFR and it is often done by measuring the amount of creatinine in a 24 hr urine collection or can be estimated by using an equation called "Cockcroft-Gault" formula. ...Read more

What creatine level or GFR level makes dyalysis necessary?

What creatine level or GFR level makes dyalysis necessary?

Ten: It is generally accepted that a GFR of 10 or less or a serum creatinine level of 10 or higher to the point at which dialysis is started. However, dialysis is started when all other therapies have or are failing and the only alternative left is dialysis. Why? Because dialysis is a huge life changer for anyone irrespective of age. ...Read more

What is the difference between creatinine clearance and inulin clearance?

Practicalities: Inulin is a strange sugar from the root of chicory and dahlias. It's a researcher's tool for a somewhat more accurate estimate of glomerular filtration than is offered by creatinine clearance. The latter, however, is readily available from blood and urine samples and requires no injection, so it's what is usually used clinically. ...Read more

High value of creatinine clearance.Serum creatinine 0, 8mg/dl.Creat. Clearance 165ml/min.Normal value from 80 to130.What's the relevance of high value?

Don't worry: A high estimated GFR means nothing whateve except that the estimate has little to do with reality. The fad for estimating glomerular filtration rates in healthy people based on a correlation with serum creatinine is unscientific and has many pathologists and nephrologists unhappy. Ignore it. ...Read more

Protein Urine Random 35 Creatinine, Ur  143.0 Protein/Creat Ratio 0.2 mg. commet Nephrotic ratio> 3.5 No standard values given. kidneys ok??

Protein Urine Random 35  Creatinine, Ur  143.0 Protein/Creat Ratio 0.2  mg.  commet Nephrotic ratio> 3.5   No standard values given. kidneys ok??

Proteinuria: Protein/creatinine ratio of 0.2 is within the normal reference range. So, there is no significant increase in urine protein. I am concerned about hematuria and painful joints. Is hematuria repeatedly present? Is BP normal? Why swollen feet? What other testing has been done? Is ANA present? Have you had a recent infection? Is serum creatinine changing? Is urine albumin/creat ratio known? ...Read more

How to reduce bun creatine ratio?

How to reduce bun creatine ratio?

Don't treat a lab: Bun/creatinine ratio varies with hydration, diet, and kidney status; if high and the person's kidneys aren't working well, they may just be dry or shocky. You can lower your ratio simply by drinking a few glasses of water. But why? There's no point. I eat a lot of protein and mine tends to be a bit high, but that doesn't mean i'm sick. The big picture is everything. ...Read more

High bun and bun/creatinine ratio results? Dangerous?

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.Your doctor determines its significance. ...Read more

Serum creatinine 0.49mg/dL, 24h urine cr 22.1mg/dL & cr excretion 884mg, cr clearance 125.4mL/min, random urine cr 109,7mg/dL. Normal? If low, why?

Just ignore this: Labs are set so that a few percent of healthies fall outside on either end. This could not be due to illness. Be thankful for a normal creatinine clearance and that your physician took time to check it. ...Read more

Here are some ...: These reports alone represent your current attainable / acceptable, stable range for your body homeostasis.

Glomerular filtration & renal clearance, what is this?

Glomerular filtration & renal clearance, what is this?

GFR: Glomerular filtration is is the amount of filtering that occurs in the glomeruli of the kidney. We use this number (usually an estimation based on creatinine, age, race, sex and albumin) to determine how well the kidneys are functioning. It tells us how much kidney function (or clearance) someone has. ...Read more
