What is my risk !? Is my doctor wrong !?

[Chelsea107]

Hello guys

Let me start with my story

In 25/5/2014 i took the first dose of HBV vaccine as a part of my new job

But  i left the job after just 2 weeks and i forget to take the second and third dose .

(So i just took one dose . )

In 1/11/2014 i got stick by needle in a park  and i want to general hosptial and they did a full blood test they found my

HBs ab  >168

So the doctor but me in PEP for HIV and he said i dont have to worry about HBV because i have antiboday  .

But today while i was reading in the internat i found some people wrote that the Level of HBs ab Has to be more than 100 to be in safe side .

My questions are .

If the needle had HBV and my Hbs ab level around >168 . Am i protect from Hbv!?

What is the chance my HBV antiboday (168) will fail to fight the virus !?

Am i going to have HBV !?

Many thanks
And please i can not wait to read your comment

i know that s why i said "since this is delicate i prefer not to try conversion", all machines have different methods and even if the same unit is used results are different

we could use conversion if you know that the machine is architect or elecsys, in that case we can assume that UK uses different ranges on its own for immunity

for example for hbsag quantitative we have to use always the same machine because architect doesn t give exactly same numbers as elecsys although both iu/ml

Stef, I do not want to make a fool out of you but you do know miu/ml and iu/l is the same thing? It's just different metrics. So his 168 hbsab is in fact 168 iu/l

[stef2011]

best thing is that you retest with architect for both hbsag and hbsab, then if you find hbsab less than 10miu/ml just have vaccine again

[stef2011]

Stef, no there is no error. Great Britain (England) have 100 iu/l as stated protection.


you see machines are different and unit is different, the unit is miu/ml not iu/l.i think UK allows the use of obsolete machines.

public healthcare of italy is forced to use latest technology at least from 2000 like architect, elecsys or siemens because older machines before 2000-2005 cannot detect all hbsag types with a very high rate of false negative.
it is also a market law, if you get wrong results you can sue the lab/hospital and have very big refunds.....

anyway the unit used is not international standard so we cannot help you unless you test with normal machines and normal unit miu/ml, since this is delicate i prefer not to try conversion

Stef, no there is no error. Great Britain (England) have 100 iu/l as stated protection.

[stef2011]

i think there is a mistake in the document requiring hbsab>100miu/ml for protection or the test used is different and not in miu/ml.hbsab>10miu/ml is more than enough to protect from infection

Chelsea,

First, Your doctor seems overly worried. PEP was not needed. Blood in an old syringe is no way for HIV to spread, you can feel 100% confident you will not get HIV from this event.

Second, Great Britain is one of the few country's recommending >100 iu/l HBsAb for protecting against hepatitis B. CDC in the US says >10 iu/l is enough, and so does the majority of western unions.

You are protected. You will not get Hep B from this event.

You should however also test for Hepatitis C
