The thyroid gland is an endocrine organ located in the front part of the neck. Its role is to make thyroid hormones, which control the way cells use energy. Hyperthyroidism results when the thyroid gland is overactive and too much thyroid hormone is produced, which speeds up metabolism.

Doing creatinine clearance test is pain in the a#@?

Peeing in a bottle:): Creatinine clearance is an exact measurement of renal function, much more accurate than calculation made from serum creatinine alone. The 'pain' i guess you are referring to is that to do the test accurately requires collecting every drop of urine in a special bottle given by the lab for 24 hours. Enjoy the challenge-:). ...Read more

Creatinine clearance: The most common cause is improper urine collection which means all the urine is not collected in the container. The other reason could be not collecting blood specimen for serum creatinine once you finished the urine collection. Another reason could be not collecting urine in proper container and the last reason can be not writing the correct total volume of the urine. ...Read more

Are creatinine clearance and GFR the same thing?

Sort of: The true glomerular filtration rate is very hard to measure. The creatinine clearance is a practical way of measuring it, which requires a timed urine collection and a blood sample. It is much more accurate then the crude and subscientific estimate of the glomerular filtration rate / GFR from a spot creatinine. ...Read more

Is there a relationship between creatinine clearance and GFR?

Yes: True glomerular filtration rate is very hard to determine, but it can be estimated crudely using the creatinine clearance, which looks at serum and urine creatinine concentrations in a timed and volume-measured urine. This in turn is far more accurate than the subscientific estimate of GFR that's often part of a lab panel. ...Read more
