Each subject receiving an injection will have five separate blood samples taken, which will be analyzed separately. Each of the five measurements will be conducted in duplicate with the BVA-100 instrument and the BVA-200 instrument. Sufficient blood will be withdrawn at each phlebotomy to permit such duplicate measurement.\n\nSubjects will be enrolled who have been prescribed a blood volume procedure using the BVA-100, as a result either of their ordinary diagnostic care or of their participation in another study that uses blood volume measurement. Subjects will be adults under treatment for conditions normally associated with the need for volume assessment, such as Heart Failure, or scheduled to receive BVA-100 measurement as part of another study. An effort will be made to ensure a range of ages and a balance of the sexes.\n\nSubjects will be enrolled and consented sequentially. The University of Tennessee Medical Center site will document any patient who is not enrolled in the study sequentially and the reason why or who declines enrollment. Demographics of patients not enrolled will be collected to permit identification of any trends in non-enrollment. We do not anticipate any sequential patient not being offered the opportunity to participate in order to assure that there is no bias in selection of patients (\"all-comers\")."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "minimumAge"=>"18 years", "samplingMethod"=>"NON_PROBABILITY_SAMPLE", "studyPopulation"=>"The proposed study will be open to any volunteer meeting the inclusion/exclusion criteria listed below.
