Term Description

This test is for the tubular extraction rate (TER) based on the clearance of a radioisotope (e.g., 99mTc-MAG3). The TER can be calculated using various algorithms, including continuous infusion, single injection, single sample, and the two-compartment model. PMID: 11545186. Clearance calculation methods may differ for children PMID: 1831838. Radioisotopes, such as 99mTc-MAG3, provide evidence of tubular clearance because 99mTc-MAG3 is selectively filtered by the renal tubule and not by glomerular filtration. Tc-99m Mertiatide (99mTc-MAG3) is also a radiopharmaceutical used for renography PMID: 11545186. To report the results of a renography study (and not TER measurement), use LOINC 39746-3.

LP20516-8   1.73 sq M
The average (normal) BSA for an adult is take today 1.73 square meters. so this value is often used as an adjustment in the cases where BSA adjustment is needed and the exact BSA is not known Source: Regenstrief Help

LP262553-3   Tubular extraction rate
The tubular extraction rate (TER) is a quantification of renal function that is used for the evaluation of nephro-urological diseases. TER estimates the plasma volume cleared by the kidneys by measuring the clearance of substances that are not be filtered by other renal structures, like the glomerulus.
