I’m assuming you’re referring to a hepatitis C antibody test.
Your result may have something like
RANGE LAB
Hep C Virus Ab <0.1 0.0-0.9
Which is the range for a negative test your score of 0.3 likely also had the word negative. If that is the case you do not have hep c congrats. For a better answer you should ask your personal physician.
Hep c is a very slowly acting illness taking many years to decades for most people to develop serious liver disease.
They say that about 20% of people infected with hepatitis C for 20 years may develop liver cirrhosis.
For myself I had hep c for 30 years before I was diagnosed with liver cirrhosis 14 years ago. I was finally cured with the new treatments approved in 2014 so I’ve been hep c free for 6 years now although I still have liver cirrhosis now for 14 years.
Hep c is a blood borne illness meaning hepatitis c infected blood must enter the blood stream of an uninfected person.
While hep c is not strictly considered to be a sexually transmitted illness for those with multiple sexual partners or those who engage in rough sexual practices like BSDM or blood sports there is an increased risk of transmission. The best way to avoid this risk is using appropriate protection ie condoms.
The most common method of transmission of hep c is sharing IV drug needles with someone infected with hepatitis c.
Also with the release of new medicines approved in the last few years hep c is today curable for most people. The new medicines boast cure rates approaching 98%. Today there are many fewer people with hep c than there were before these new medicines were approved so your odds of contracting hep c are that much less and your odds of cure if you should become infected are now very high.
I hope this answers any questions you may have.
