It appears that at some time in your life you may have been exposed to the hep c virus so your body has banufactured antibodies to fight the virus. You may have even had hep c but you were one of the 25% of people fortunate enough to beat the virus on your own. That you don't have hep c is evidenced by your not detected test for the hep c virus itself the HCV RNA by PCR test.
Hep c is not considered by the CDC to be a sexually transmitted illness although there have been a few cases mostly for those who have multiple sexual partners, engage in rough sex practices or in the presence of HIV. In fact the CDC does not suggest that long term monogamous couple will need to use barker protection as sexual transmission in such couples is practically non existent. There are many who have hep c while their spouse does not.
Hep c is a blood borne virus that requires blood to blood contact to be transmitted.
As to why you are testing positive for antibodies to hep c is anyone's guess there are a small percentage of people who are or were infected with hep with no idea how they became infected. This may be your situation or a possible rare false positive. But as you have tested positive for antibodies a couple of times you will likely always test positive for antibodies for the remainder of your life. Antibodies are not the virus that are made by your body in response to coming into contact with the hep c virus. Hep c antibodies are a part of your own immune system much like if you either had measles or were vaccinated against measles you have antibodies to the measels virus in your blood.
So in my thinking any additional testing for hep c antibodies are a wasted effort as the likely result is know you will test positive for hep c antibodies. The only way to know if you are currently infected is to have the test for the virus the HCV RNA test. But if you haven't had any risk behaviors you likely will never test positive on an HCV RNA test.
As for your child if you do test not detected on the HCV RNA test you have no virus to transmit. Even if somehow you do test detected for the hep c virus there is only about a 5% chance of transmission to your unborn child during birth.
But if you do test positive on the HCV RNA test other than getting treated to cure your hep c you would want to consider having your child tested due to the low risk of transmission during birth. But that testing would only be needed if you are currently infected with hep c and not nearly positive for antibodies.
In answer to your specific questions:
1.What are the chances of HCV RNA tests come back positive since it was negative in Nov last year.
Hard to say but I anticipate if you had no risk of blood to blood contact I would be very surprised if you test positive for the hep c virus having tested not detected in the recent past.
2.since I've zero risk factors for getting it in my whole life rather than my pregnancy, does it mean I get it from my husband. (He was also negative until 2015 as he donated blood and he doesn't know his current status ).
As above hep c is not considered to be sexually transmitted for long term monogamous couples. It is a blood borne virus requiring blood to blood contact. You will likely never know why you test positive for hep c antibodies.
3.should I get my baby checked too. he's a boy 2 months old now.
Only if you test positive on the HCV RNA test showing you are currently infected with hep c.
I hope that helps you to understand better what is going on best of luck and congratulations on your new baby.
Thanks again for such a positive insight .. I pray that what you are assuming about being non detected for current disease, become reality..
It's so overwoverwhelming for me to being exposed to it unknowingly.. my second guess of getting it by not properly sterilized instruments they used during first prenatal testing (pap smear).. I wish I could know the real source. Healthcare should be sued if it's really the case .
When I went there for my blood drwa for HCV RNA tests ..she only filled one vial and sent me home .when after five days ,I called laboratory about results ,they told me blood wasn't enough to do testing so you come again . And no one bothered to call me to let me know they need more blood until I call myself. And they drew four vials.
I really appreciate your concern for so many ppl like us giving them information and also encouragement. Your reply really brought my anxiety levels down for upcoming results. Thank you for this .
Yeah ,it's not same as a cancer ,but being through it for my daughter seeing her in pain n begging me to do something to give her relief .. is already so much to deal with rest of my life let alone more issues..
For last couple of weeks ,I find myself drenching in cold sweats upon waking up so much so that most of my clothing would be literally wet and sweat running through my skin like water .it was never like that before . I'm so messed up emotionally too . I wish I could show you my daughter's picture. She was SO precious, so loving and caring .. so full of life .. Life is already very hard without her .
Last words on her lips when she left this earth in front of my eyes were Mama Mama ..I would wonder for the rest of my life what she was going to say and couldn't complete her sentence.. oh my baby.. miss you so so much.
