A Comparator Study of a Tasso Device Blood Sample to Traditional Venous Blood Sample for CBC

N/ANot Yet RecruitingNCT06360952

Tasso Inc.40 enrolled

Overview

This study will evaluate the feasibility of using capillary blood samples collected with the Tasso device for analysis of CBC in diseased patients with leukemia, lymphoma, and/or other blood cell disorders. This investigation will include a minimum of 40 sample sets from unique patients. The primary aim of this study is to demonstrate the agreement between capillary blood collected using the Tasso device and venous blood collected in a K2EDTA (dipotassium ethylenediaminetetraacetic acid) tube according to established sampling procedures for quantification of WBC and ANC as part of a standard CBC panel with 5-part differential. The secondary aim of the study is to demonstrate the agreement between Tasso device and venous samples for the measurement of additional analytes evaluated as part of a standard CBC panel with 5-part differential, including PLTs, HGB, RBC, Hct, MCV, lymphocytes, monocytes, eosinophils, and basophils. An exploratory aim of this research is to evaluate patient acceptance of the Tasso device in a diseased population. Adverse Events (AEs) occurring up to 24 hours after use of the Tasso device will be evaluated. Patient response to using the Tasso device will be collected via simple survey.

Outcomes

Primary Outcomes

Agreement between capillary and venous blood in the measurement of White Blood Cells and Absolute Neutrophil Count

To demonstrate agreement between capillary blood collected using the Tasso device and traditional venous blood collected using standard methods for measurement of white blood cells (WBCs), and absolute neutrophils count (ANC) as part of a CBC analysis with 5-part differential.

Time frame: Day 1

Secondary Outcomes

Agreement between capillary and venous blood in the measurement of secondary biomarkers

To demonstrate agreement between capillary blood collected using the Tasso device and traditional venous blood collected using standard methods for measurement of remaining CBC components including platelets (PLTs), hemoglobin (HGB), red blood cells (RBCs), hematocrit (Hct), and mean corpuscular volume (MCV), as well as differential quantification of lymphocytes, monocytes, eosinophils, and basophils.

Time frame: Day 1
