11. The learned counsel for the petitioners has contended that if urine samples are to be tested for the presence of drugs, there must be a confirmatory test of those tested urine sample by either of the two methods - Gas Chromatography or Mass Spectrometry. In the case at hand what is being sent is testing of urine samples. The test report is quoted hereinabove. It is admittedly not tested by either of the methods as noted hereinabove. A coordinate Bench of this Court in SRI PRANAY NATARAJ V. THE STATE OF KARNATAKA in W.P.No. 7178 of 2024 disposed of on 29-05-2024, considers this aspect and holds that urine samples must be confirmed by the afore-quoted two tests. The coordinate Bench, in the said decision, holds as follows:

NC: 2025:KHC:49643 HC-KAR Independent analytical techniques of which one should be instrumental. So, it is mandatory to follow alternative methods like Chromatography and Spectroscopy. Gas chromatography (GC) and High performance Liquid Chromatography (HPLC) offer high sensitivity and specificity for confirmation of presumptive results in screening tests. Gas - Chromatography-Mass Spectrometry (LC-MS) are the most most sensitive and specific methods for confirmation of drug presence in a sample. The Spectroscopic methods are FT-IR with standard library/control and UV-Vis Spectrophotometer with control sample. At present, from among the above mentioned sophisticated and costly instruments Gas Chromatography (GC) and High performance Liquid Chromatography (HPLC), FT-IR with standard library/Control, and UV-Vis Spectrophotometer with control samples are made available to all the units where the examination of the narcotic substances is being carried out except for District Level Laboratories where only the examination of Ganja is being carried out. All the basic requirement concerning instrumentation are made available at FSL and RFSLS."
