ARK Methylphenidate Metabolite Assay
This homogeneous enzyme immunoassay by ARK™ Diagnostics enables the quantitative determination of ritalinic acid, the primary metabolite of methylphenidate. It offers an efficient alternative to more time-consuming chromatographic methods and is ideal for monitoring patient compliance or detecting abuse. The assay is compatible with all major clinical chemistry analyzers and can be easily integrated into a lab’s existing drug screening routine.
Assay Characteristics
- Highly specific detection of methylphenidate misuse in urine
- Rapid and sensitive screening method for the monitoring of patient compliance
- Cut-off 100 ng/mL
- Liquid, ready-to-use reagents, calibrators and controls
- Application protocols for all major clinical chemistry analyzers
Background
Methylphenidate is a psychostimulant that acts as a dopamine and noradrenaline reuptake inhibitor. It is primarily used for the treatment of ADHD and is available in Germany as a legal and prescribable narcotic on a BtM prescription.
The mechanism of action is similar to that of cocaine or amphetamine – it is not for nothing that methylphenidate is considered a ‘speed substitute’ in the drug scene. The tablets are usually taken orally, snorted as a powder, or dissolved in water and injected. The energizing and stimulating effect lasts for around four hours. During this time, performance and concentration are increased, while the body loses the ability to perceive exhaustion or overexertion.
