Laboratory tests for gamma-hydroxybutyric acid (GHB) in serum or urine are not readily available. The diagnosis is made by history and physical examination. Reference laboratories can perform...

If the GHB Screen, UR is non-negative, then the Gamma-Hydroxybutyric Acid, CF, UR (FGHAC) will be performed at an additional charge. Specimen Type Describes the specimen type validated for testing

γ-羟基丁酸，又称 4-羟基丁酸， （gamma-Hydroxybutyric acid，GHB），是一种在 中枢神经系统 中发现的天然物质，亦存在于 葡萄酒 、 牛肉 、 柑橘属 水果中，也少量存在于几乎所有动物体内 [1]。 该神经药物因无色无味並会導致暂时性记忆丧失、 噁心 、呕吐等症状，而被犯罪分子用作 麻醉药品 或 迷姦药物，中文又稱 神仙水 、 聽話水，或 迷姦水 、 G水。 γ-羟基丁酸可在人体细胞内合成，结构上与 酮体 β-羟基丁酸 相似。 在实际使用中，通常使用γ-羟基丁酸的 钾 盐或 钠 盐 …

GHB (enzymatic assay) The enzymatic GHB assay is a three reagent test which can be applied on clinical chemistry platforms. For modern mid/high throughput analyzers a simplified two-reagent protocol is possible.

There are increasing reports of abusing Gamma-Hydroxybutyric acid (GHB). GHB is also typically associated with sexual assault or as a "date rape" drug due to its severe hypnotic and sedative effects at higher dosages. Typical illicit use of GHB involves dissolving 2-3 …

This is a qualitative test to detect the presence of GHB. A positive result indicates the ingestion of GHB or Gamma-butyrolactone (GBL) or 1,4-Butanediol. GHB has a very short half-life and urine should be collected as soon as possible after a suspected ingestion.
