The purpose of this study is to compare the results for HIV and/or Hepatitis C Virus antibody testing when using routine plasma versus SMARTplasma from the same blood sample. SMARTplasma is enriched for antibodies via a stimulation step of whole blood in a SMARTube™ (SMARTstim™ in the USA).

Primary Objective:
To determine the clinical sensitivity and specificity of the Biomoda CyPath™ Early Lung Cancer Detection Assay using sputum specimens from two cohorts of participants and estimate the required sample size to finalize a protocol for a pivotal study.
Secondary Objectives:
To assess the capability of the Biomoda CyPath™ Early Lung Cancer Detection Assay in a clinical setting to identify cancer cells, as assessed by TCPP labeled cancer cells demonstrating red fluorescence under a microscope with ultraviolet (UV) light being observed with a FITC (Fluorescein isothiocyanate) Filter.
To assess the capability of the Biomoda CyPath™ Early Lung Cancer Detection Assay to detect pre-invasive cancer in comparison with PAP sputum cytology and routine CT scan.

The purpose of this study is to determine whether transcutaneous electrical nerve stimulation (TENS) delivered via the Empi Select TENS device provides relief of chronic lower back pain.
