The Mobile Medical Unit (MMU) facilitates health care delivery for people in rural areas of Thailand by transporting a health care team and small laboratory directly to where they live. The goal of this study was to use the MMU and point-of-care testing to screen for hyperglycemia, hyperlipidemia, and thalassemia trait. We measured glucose, total cholesterol, and triglyceride in serum using photometers on the MMU. Thalassemia trait was diagnosed by osmotic fragility (OF) and dichlorophenol-indophenol (DCIP) tests. We found that 10.7% of people screened had blood glucose higher than 110 mg/dL, and 5% had higher than 125 mg/dL. We found that 17.8% had total cholesterol higher than 250 mg/dL, and 32.0% had higher than 150 mg/dL. Of the samples, 37.5% yielded positive OF and DCIP tests; 20.2%, positive OF test only; 10.8%, positive DCIP only; and 31.5%, both negative. Heterozygous hemoglobin E was identified in 69 (52.7%) and homozygous hemoglobin E in 15 (11.4%) of 131 subjects. The Naresuan University MMU can be used efficiently with point-of-care testing for hyperglycemia, hyperlipidemia, and thalassemia trait screening in public health.
