Metabolic syndrome

 A 34-year-old male with schizophrenia, started on quetiapine 6 months ago with partial response thus far. All appropriate laboratory work had been performed at that time and was within normal limits. Previous adequate trials of antipsychotics include asenapine, which was ineffective. He is also on lisinopril for hypertension. Explain which laboratory work is appropriate for monitoring of metabolic syndrome?
