As a basic screen for jaundice, please get the following tests done:
- Serum bilirubin (total & direct)
- Serum AST, ALT (& GGT) and alkaline phosphatase
- Serum protein levels
- Tests for hepatitis B viral markers like HBsAg, anti HBe etc.
- Maybe an abdominal ultrasound.
But this cannot be decided by e-mail. Please show yourself to a doctor who will take a history and do a clinical examination, as this will suggest what tests need to be done.
I am not trained in Ayurveda and am not competent to comment on that.
