Lab work 6/60
A 6/60 is an another term for electrolyte and renal function tests: Na, K, Cl, HCO4, BUN, and creatinine.
The term 6/60 comes from a laboratory analyzer called a Sequential Multiphasic Analyzer 6/60, made originally by the Technicon Instruments Corporation in the US in the 1960s and used for decades afterward. It is an automated multichannel chemical analyzer. Its novelty was that it could do more than one test at a time. The term 6/60 became synonymous with the lab tests done by the machine.
