Study start date: May 13, 2019

Actual date on which the first participant was enrolled.

This is a cross-sectional diagnostic accuracy study with up to 250 participants with a goal of obtaining 20 deficient and 20 intermediate samples. The clinic will recruit and consent study participants. Clinic staff will draw 3 whole blood samples and obtain finger stick capillary blood. G6PD activity is reported in terms of grams of hemoglobin (Hb), hence the hemoglobin concentration must be measured. Clinic staff will perform the investigational Standard Diagnostics (SD) Biosensor point-of-care (POC) test for glucose-6-phosphate dehydrogenase (G6PD) deficiency and a HemoCue® hemoglobin test on finger stick capillary blood and on the venous blood samples. Another venous blood sample will be sent to a clinical laboratory improvement amendments (CLIA)-certified laboratory for reference testing by the gold standard assays: * G6PD measurement by spectrophotometry using the Pointe Scientific G6PD reference assay * hemoglobin measurement by a hematology analyzer Individuals identified as G6PD deficient with the reference test will be notified of their results by the clinic and referred to their physician for follow-up.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

250 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Diagnostic Study

Diagnostic studies focus on improving how we detect or confirm a disease. They test new tools or techniques that could provide faster or more accurate diagnoses.

This study does not include a placebo group 

Treatment Groups

Group I

Participants provided whole blood samples as well as fingerstick capillary blood samples. At the clinic site lab, study staff conducted the SD Biosensor point-of-care G6PD test and the point-of-care HemoCue Hb test on both finger stick blood and whole blood samples. At the reference laboratory, G6PD activity was measured from whole blood samples using the Pointe Scientific G6PD reference assay and hemoglobin was measured using a hematology analyzer.
