The UPEP or the SPEP are tests done upon the Urine (UPEP) or the Serum samples (SPEP) to detect proteins
. The Nicotine
test also called as Cotinine test, which is used to detect the levels of Cotinine, a product of tobacco smoking
. The Cotinine levels varies with smokers and non smokers and basically this is tested in the Urine using a kit that is available in only few specific laboratories across India. Thus, the UPEP or SPEP is not the test to identify the Nicotine or Cotinine. I hope this answers your query and would be glad to answer if you have any other queries with regard to the Cotinine test.
Thank You and Take Care.
