A Follow-up and confused by labs
« on: February 07, 2010, 02:15:39 AM »
This is a follow-up to the situation when I was in the hospital.  I've contacted the president of the hospital again about that problem.  That's not what I'm asking about now.  I got a full report of my labs from the hospital.  It was printed off by an office worker, so I haven't had the opportunity to question a medical professional.  Getting these labs did shed light on many things.  I didn't know I was tested for just about everything..all the Heps, syphilis, toxo, histo, etc.  I was retested for many of these at the HIV doc.

Anyway, I came across some things I don't understand and wondered if any of you may know.  Again, I intend to ask the doc about this when I see him.  Things I'm confused about and this is how it is printed on labs:

Hep Bs Antigen:  Negative
Hep Bs Antibody:  <5.0  (Had an icon next to this meaning there is info to be accessed regarding this)

Urine Histoplasma Ag:  Neg
U Histoplasma Ag Intrp:  <2 (Had the same icon meaning more info to be accessed)

Then it goes on to list other tests like CMV and will list it as Negative.  However under Cryptococcal Antigen, it is blank.  I don't know whether poz or neg for this.  I know I will have to do research into this at the hospital.  It also had the HIV Viral Load blank.  It would be so helpful to know vl while sick.  This is something I'll have to see why it isn't listed at the hosptial as well.

Under Fungal Culture it says "Candida Albicans".  I would think this means thrush??  I remember the doc saying he didn't find any sign of thrush.

It was interesting to see how whacked out all my labs were while sick--such as WBC, RBC, well just about all CBC numbers were way out of whack and my sugar was like 180 while sick.  I just don't know what the Hep B or Histo info means.  What do those numbers next to them mean, if anything?  At the HIV doc, they said I was neg for Hep A,B, and C. 

Okay, just thought someone would know what these mean before I have a chance to ask doc.

Thanks everyone.

Well the Hepatitis B results (there are two there) seem ok.

HBV is a complex virus with loads of different components. Identifying these components and the body's response to them is important in telling if a person has been infected with HBV or merely been vaccinated.

Hep Bs Antigen (aka HBsAg) refers to the Hepatitis B Surface antigen - which is a component of the virus found (as the name suggests) on the outside of the virus. Negative means none was detected which is good. A positive HBVsAg means a person has active Hepatitis B.

Hep Bs Antibody (aka HBsAb) refers to the Hepatitis B Surface antibody which is what the immune system produces in response to the presence of the surface antigen. <5.0 tells us that the test found that your sample contained less than 5 of whatever units the consulting laboratory uses to measure levels of HBsAb.

This is usually referred to as the General Mean Titre (GMT). A GMT of less than 5 means you are not immune to HBV. In fact it probably means that there is no HBsAb  present at all. This tallies with what the doctor told you.

HBV has other antigens (and there are corresponding antibody that are produced in response to them) but that information is beyond the scope of your OP and I won't cloud the issue with a discussion of those.

Very often laboratory results give reference ranges, meaning that if your results are below a certain value you are deemed negative for the given condition.

I've got no particular experience with Histoplasma Capsulatum testing so I won't attempt to speculate about those results. There are other members here who have survived Histo and can give you the straight poop on that subject.

Yes, Candida Albicans refers to thrush.
