Hemoglobin; Deficiency
Conditions
Brief summary
Blood hemoglobin levels are an extremely important measure for a large swath of medical procedures as they reflect the oxygen-carrying capacity of human blood. The gold standard measure for blood hemoglobin levels involve a venous blood draw followed by a laboratory-based complete blood count (CBC), a process which is both painful and time consuming. To date, various methodologies have been tested to either expediate the process or provide a non-invasive alternative. There remains a need to provide a quick, pain-free/non-invasive and accurate modality to measure blood hemoglobin levels. The objective of this study is to determine whether computer vision technologies can be applied to fingernail images captured via a smartphone camera to quantify blood hemoglobin levels.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| To determine whether computational learning methods can be applied to fingernail images captured via a smartphone camera to quantify blood hemoglobin levels. | 6 months | Evaluated using the hemoglobin portion of a conventional complete blood count (CBC) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| To determine whether computational learning methods can be applied to fingernail images captured via a smartphone camera to screen for anemia as defined by the WHO | 6 months | Evaluated using the hemoglobin portion of a conventional complete blood count (CBC). Anemia cutoff for children aged 6 months to 6 years = 11 g/dL and for children aged 6-14 years = 12 g/dL. |
| To determine whether computational learning methods can be applied to fingernail images captured via a smartphone camera to quantify other elements of the CBC | 6 months | Evaluated using the hemoglobin portion of a conventional complete blood count (CBC) |
