Question

CRITICAL THINKING APPLICATION What tests are routinely done as part of the renal panel? What information will these tests give Dr. Fischbach about the status of Mr. Corrigan's kidney? What color of rubber stopper or plastic stopper on vacuum tubes would need to be drawn for a serum specimen that will be processed and sent to the reference lab? (Hint: There are three colors based on plain "cdot" tubes and SST tubes. How will you know which serum tube to use?) 47-7

Answer 1

The three major components of primary renal panel are BUN, creatinine and urine specific gravity. Creatinine is a good indicator of GFR Increase in creatinine is decreasein glomerular filtration. Decrease in creatinine is increase in glomerular filtration. BUN is a good indicator of GFR. Increase in BUN is decrease in glomerular filtration. Decrease in BUN is increase in glomerular filtration.

SST tubes can be used to collect a serum specimen . Red-top tube contains no anticoagulant or preservative and it is used in serum or clotted whole blood. Serum must be separated from cells within two hours of venipuncture.
