Doctor, I am currently taking  ARV full PEP following a dog scratch (no bleed, minor...)...I was actually parking my bike and wearing a helmet...dog (it was likely a pet....I am unsure if it was stray or not) came running from behind and touched my foot (I have dry skin in my feet/few cracks are there..not open tough..due to dry season), there was no open deep wound/bleeding. I immediately washed with running water first, then came back home with dettol soap + water. Went to the nearest hospital, and got ARV dose (Rabivax S).. The physician told me to get all shots (without RIG) I have taken 3 doses till now (Rabivax S) Previously around 5 months back in Mid November 2025, I was immunized with Abhyarab full PEP...5 doses (for a  rodent scratch....also took TT ). Can I check my antibody titres, is the ELISA Test from Agilus Diagnostics valid? If so when, can do it ?
