Samsung Study (2026)
Evaluates whether extracellular water and total body water measured by Samsung Bioimpedance Analysis (BIA) devices are accurate compared to standard tests including the dilution method and dual-energy X-ray absorptiometry (DXA). Includes BIA, DXA, 3D optical scan, Bod Pod, biological samples (urine, saliva, blood), and a diet questionnaire.
- Eligibility
- Healthy adults; no removable metal, jewelry, or incompatible medical devices, and no chronic disease. Recruitment uses age and BMI categories — see the BMI calculator to estimate yours.
- Commitment
- Single 4-hour appointment

Tanita Study
Evaluates the accuracy of TANITA Bioimpedance Analysis (BIA) devices for measuring extracellular and total body water — compared against standard methods like dilution analysis and dual-energy X-ray absorptiometry (DXA). Includes BIA, DXA, urine/saliva/blood samples, 3D optical scan, Bod Pod, and a diet questionnaire.
- Eligibility
- Healthy adults; no non-removable metal, jewelry, or medical devices, and no chronic disease.
- Commitment
- One ~4-hour visit, Mondays–Fridays at 7:30 AM check-in

Comparative studies in body composition
Evaluates cardiorespiratory fitness, body composition, and muscle strength in healthy adults using several assessment tools, including Dual-Energy X-ray Absorptiometry (DXA), treadmill-based aerobic fitness testing, 3D optical scanning, air displacement plethysmography, and strength measurements. Additionally, the study assesses the repeatability and variability of these laboratory methods. Results will help investigators better understand how consistent these measurements are when performed within the lab and support the use of these technologies in future research.
- Eligibility
- Healthy adults; no non-removable metal, jewelry, or medical devices, and no chronic disease.
- Commitment
- Between 30 minutes and 2 hours.

Makawalu Study
Closed for now; expected to reopen — get in touch to be notified.
A pilot study evaluating a handheld portable ultrasound device (Clarius HD3 L15) integrated with AI for breast-cancer detection — comparing its performance to traditional mammography. The research aims to enhance screening accessibility in remote and underserved Pacific communities. "Makawalu" means "eight eyes" in Hawaiian — symbolizing examination from multiple perspectives.
- Eligibility
- Women 18+ with a mammogram scheduled within 6 months. Not currently pregnant or breastfeeding. No breast augmentation or implants.
- Commitment
- One-time, 1-hour Saturday visit at the UH Cancer Center
