I had a urine analysis done and the results read urine cox 1/19 what does this mean?

Not urinalysis: I don't know what you are looking at but a standard urinalysis includes specific gravity (SG), pH, blood, nitrites, leukocyte esterase, ketones, glucose, protein, and then, if indicated a microscopic cell count that includes red and white blood cells, squamous cells, crystals, and misc debris. COX1 and COX 2 (not Cox) are inflammatory pathway metabolites measured in urine for research purposes.
