Runs on Automated Clinical Chemistry Analysers
Clozapine is the most effective antipsychotic drug for reducing positive symptoms, hospital admissions, and all-cause mortality in patients with schizophrenia.1 Saladax’s test offers clozapine blood levels within hours instead of days.
Intended Use
The MyCare Psychiatry Clozapine Assay Kit is intended for the in vitro quantitative measurement of clozapine in human serum and plasma using automated clinical chemistry analysers. Measurements obtained are used for monitoring patient adherence to clozapine therapy to help ensure appropriate treatment.
Obtaining timely clozapine drug levels is a significant barrier to clozapine use.2
Drug level monitoring may reduce the risk of relapse or recurrence by increasing the doctor’s awareness of the patient’s adherence to the medication.3
TDM-based prevention of atypical antipsychotic overdosing is, for the majority of patients, a matter of the patient’s quality of life rather than of safety.3
Clinical guidelines strongly recommend routine monitoring of clozapine drug levels in blood.3,5

Expected Values
As for any laboratory test, the clinical context should be taken into consideration when interpreting clozapine results. Compare assay results to results expected based on previous measurements, subject’s baseline, suggested therapeutic range, or values expected for the individual. Clozapine has a recommended therapeutic reference range of 350 – 600 ng/mL. Guidelines strongly recommend therapeutic drug monitoring for clozapine.1
