Participants with any of the following criteria will be excluded:
1. Any ongoing, symptomatic acute illness requiring medical or surgical care or chronic illness of moderate or severe grade including HIV Stage III/IV or chronic illness/disease that is not stable (at the discretion of the investigator). Acute illness is a temporary exclusion for which the participant may be re-evaluated once they improve or recover.

3. Unstable or Severe Chronic disease inclusive of:
a. Hypertension (elevated blood pressure [SBP>155mmHg or DBP>100mmHg]). Note that participants can be retested once after resting or return on another day for retesting.

14. Known disturbance of coagulation (iatrogenic or congenital). Note: The use of low-dose aspirin (≤ 325 mg/day) as prophylaxis is acceptable in dosages consistent with local standards of care, but the use of other platelet aggregation inhibitors, thrombin inhibitors, Factor Xa inhibitors, or warfarin derivatives is exclusionary, regardless of bleeding history, because these imply treatment or prophylaxis of known cardiac or vascular disease.
