まとめ
尿または経口液(唾液)による職場での薬物検査は信頼性が高く、一般的な薬物に対する陽性予測値は80%を超えます。尿検査は、確認検査が必要なサンプルを唾液検査よりも多く検出します。
科学分野:
- 法医学毒物学
- 労働衛生
背景:
- 職場での薬物検査プログラムでは、薬物使用を抑止しリスクを軽減するために、ランダムまたは予告なしの検査が一般的に使用されています。
- 検査は、オンサイトまたはラボベースの方法を使用して尿または経口液(唾液)で実施でき、高感度かつ特異的なアッセイによる確認が行われます。
研究 の 目的:
- 尿および経口液(唾液)の薬物検査における陽性率を判断するため、12ヶ月以上のデータをレビューしました。
- 雇用主がスクリーニングポリシーの効果を評価し、確認検査が必要なスタッフの数を推定できるようにするため。
主な方法:
- 12ヶ月間の職場での薬物検査データの分析。
- 尿および経口液(唾液)サンプルの陽性率と確認検査要件の比較。
主要な成果:
- 尿検査と経口液検査の両方の一次スクリーニング結果は、一般的に使用される薬物に対して80%を超える陽性予測値を示しました。
- 尿検査では確認検査が必要なサンプルの8.9%が検出されたのに対し、経口液(唾液)検査では3.4%でした。
結論:
- 尿および経口液による薬物検査は、どちらも職場での薬物検査のための信頼できるスクリーニング方法です。
- 尿検査は薬物のない職場を確保するために、より効果的ですが、経口液検査は懲戒処分の対象となるケースが少なくなる可能性があります。

Urine Studies I: Urinalysis
1.8K
Urinalysis is a widely used diagnostic test that analyzes urine's physical, chemical, and microscopic characteristics. Healthcare providers use it to detect and monitor various health conditions, including renal disease, urinary tract infections (UTIs), diabetes, and metabolic or systemic disorders.Components of UrinalysisUrinalysis consists of three primary components: physical, chemical, and microscopic examination. Each provides unique insights into the urine sample and, by extension, the...

Urine Studies II: Urine Culture and Sensitivity Test
1.6K
A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...

Urodynamic Studies: Uroflowmetry
5.9K
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

Renal Drug Clearance: Comparison Between Renal Excretion Methods
694
Renal clearance is a critical parameter encompassing kidney filtration, secretion, and reabsorption processes. It is calculated using a specific equation to determine the rate at which the kidneys clear a drug.
Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...

One-Compartment Open Model: Urinary Excretion Data and Determination of k
706
The one-compartment open model leverages urinary excretion data to estimate renal clearance, which gauges the kidney's capacity to expel a drug. This method offers several benefits, including directly measuring drug elimination and assessing the kidney's contribution to overall drug clearance. However, this approach has limitations. It assumes sole renal excretion of the drug, which is not true for all drugs. Accurate urinary excretion and plasma drug concentration measurement can also...

Drug Dosing in Renal Diseases: Measurement of Glomerular Filtration Rate
74
The glomerular filtration rate (GFR) is a critical indicator of kidney health, reflecting how well the kidneys filter blood. Changes in GFR can signal potential kidney impairment, necessitating accurate measurement methods to monitor kidney function effectively.Various molecules can serve as markers for GFR measurement, with the ideal marker meeting several specific criteria. It must freely filter at the glomerulus, avoid reabsorption or secretion by the renal tubules, remain unmetabolized, not...
