How do you calculate true GFR?
First, GFR can be assessed by measuring during a shorter period of time the clearance of an exogenous filtration marker such as iohexol, iothalamate, 51Cr-EDTA or DTPA. This is generally regarded to be the gold standard for measuring kidney function, and therefore is often referred to as measured GFR (mGFR).
Should I worry if my GFR is 53?
Your GFR will help determine your stage of kidney disease. GFR and creatinine are usually measured and reported together. GFR is the best measure of kidney function but both creatinine and GFR can be useful indicators of your kidney health. If GFR goes down, it’s a bad sign.
Should I worry if my GFR is 45?
Your kidney function is still considered normal if the GFR number is 90 or greater. If your GFR is 45, you know that your kidneys are working at approximately 45 percent of the normal rate.
What is beta trace protein?
Beta-trace protein (BTP), also known as prostaglandin D2 synthase (PGDS; prostaglandin H2 D-isomerase [EC 5.3. 99.2]), is a low molecular weight protein that has traditionally been used as a marker for cerebrospinal fluid (CSF) leakage because it represents approximately 3% of the proteins in the CSF [1].
Which GFR Calculator is best?
Currently the best equation for estimating glomerular filtration rate (GFR) from serum creatinine in children is the Bedside Schwartz equation for use with creatinine methods with calibration traceable to IDMS1, 2.
What is a beta 2 transferrin test?
Beta-2-transferrin is a form of the protein transferrin that is present in cerebrolspinal fluid (CSF), but not usually found in blood, nasal secretions or other body fluids. It is used to distinguish CSF from other watery discharge from the nose or ear after a traumatic injury to the brain and or spine.
What is cerebrospinal fluid rhinorrhea?
Cerebrospinal fluid (CSF) rhinorrhea is a condition where the fluid that surrounds the brain leaks into the nose and sinuses. Head trauma, surgery, or even birth defects can make a hole in the membranes that hold this fluid.
