Should i redo 24 hrs urine test for catecholamines metanephrine if i had a cigarette or just give it to lab?

See below: Urine collection for metnephrines requires a lot of precautions. It would be better to redo. See the website given below for details about precautions or this test. http://labtestsonline.org/understanding/analytes/urine-metanephrine/tab/sample.
