Development of Non-Invasive Screening of Haemoglobin for Anaemia Device (NISHAD) as a Point of Care Test: A pilot study

This study will be undertaken to develop a device for non-invasive screening for anaemia. A prototype shall be developed. In the OPD/IPD, patients who have been advised Complete Blood Count (CBC) will be explained about the study. If they consent to participate, primary demographic data will be recorded and every subject (anaemic or normal) will be asked to insert their index finger in the area provided in the prototype device and keep it for few seconds. The value displayed shall be compared with the CBC reports. Data will be analysed using paired t test and significance level of p< .05 shall be considered. ROC curve will be constructed.  Area under curve, sensitivity, specificity, positive predictive value and negative predictive value shall be computed. Categorical data shall be analysed using chi square test.
