2. Screening tools: Medical Assessment, Medical History and Physical Examination. Medical assessments include: Vital Signs, EKG, oral HIV test, height/weight measurements, urinalysis and blood sample. Tests on the blood sample include CBC, complete metabolic profile, TSH, ESR, STS and HIV (if needed to confirm a positive salivary test for HIV). The following individual laboratory results will independently disqualify individuals: Cholesterol >250 mg/dl, Hemoglobin < 10.5 g/dl, WBC < 2400/microl, LFTs > 3Xnormal, HCG positive, Casual serum glucose > 200 mg/dl, Urine protein > 1+. The MAI will retain discretion to exclude at less extreme values, depending on the clinical presentation. (Serum glucose over 140 mg/dl will be followed up with a fasting serum glucose assessment. Those with fasting glucose below 100 mg/dl may be considered for the protocol. Others will be rejected and referred for work-up.) MAI will make the final judgment on any questionable lab results.
