As someone who’s spent a lot of time reading up on liver health (obsessed after a family member got diagnosed), the whole process of getting diagnosed with hepatitis is quite thorough. They start with blood tests to look for liver damage markers—mainly liver enzymes like ALT and AST. They also test for viral antibodies or DNA, depending on what type they suspect, because each type of hepatitis virus has its own characteristics and triggers. Occasionally, doctors might suggest an ultrasound or even a liver biopsy if things look serious. It’s all about getting the full picture to tailor the right treatment.
