Application of GHB Smith reagent in the detection timber of medical fluid

The present invention discloses the use of a liquid specimen Smith reagent in the detection of GHB in the material. Also discloses a method of detecting liquid in the medical timber of GHB, comprising the steps of: Smith reagent was added dropwise to the solution to be detected in the medical timber, a liquid specimen to be detected when the color changed to green sheet, the material proved to be detected in a liquid specimen candidate of GHB, and vice versa, then the candidate contain none or below the detection limit. Detection method of the present invention has high detection sensitivity, better specificity, and in cryopreservation, Smith nature of the reagents remain stable for at least six months, the reaction reliable results.
