AfyaTest(Afya mean "Health") is non-invasive method developed purposely to detect pulses and monitor blood volume changes in the microvascular bed of tissue in the fingertip/palm skin through PhotoPlethysmoGraphy Algorithm, capillaries expand and contract based on this blood volume, AfyaTest detects changes in light absorption which comes from the smartphone torch as a white LED light source to estimate heartrate, blood pressure, blood glucose-level and respiratoryRate.

1. It is Mobile Pulse Oximeter.
2. No external hardware required, its only your smartphone needed.

What are the Challenges:

1. Cold hands tend to have poor blood circulation which cause difficult in monitoring.
2. Finger Motion/Movements Detected can cause noise signals(later filtered).
3. Smartphone Camera Quality for Best Image Processing.
4. External light interference.
