Non Reactive Mean
In many laboratories: a "borderline nonreactive" result is reported as "indeterminate." A positive result is an antibody titer >12 mIU/mL; this means the individual is immune to hepatitis B. A negative result is <5.0. The CDC defines a fairly large range of indeterminate: > 5.0 but < 12.0. Indeterminate means "unable to determine immune status." Most would advise (re)immunization in this case. Stay well:) ...Read more
Yes, but you may: Need vaccination. Lack of hep b surface antigen means that there is no active infection. But you may be susceptible to infection and if you are not immune, you should get vaccinated. See this site for explanation of hepatitis b testing. http://www.cdc.gov/hepatitis/hbv/pdfs/serologicchartv8.pdf. ...Read more
Can .o4 hep c test result non-reactive mean that I could have the virus and my body hasn't made enough Antibodies yet?
Is ELISA test for HIV 1 & 2 antibodies conclusive after 8-9 weeks of exposure? Does NON-REACTIVE mean NEGATIVE?
ELISA for HIV: The ELISA test is not conclusive after any amount of time. The ELISA is a screening test and if it comes back positive, a Western blot will need to be done. Non-reactive is a good thing to be and it does mean that you are negative for HIV virus. Although there is a window period when you can have the HIV virus but still have a nonreactive result. Another test may be needed in that case. Suerte ...Read more
Depends on timing,Sx: The answer depends on the timing of possible exposure to syphilis & any symptoms (Sx) that you may have. So, it's impossible to answer your question here. Use HealthTap Prime or talk to the doctor who ordered the test. CIA, or chemiluminescence assays, are REACTIVE when treponemal (bacteria that causes syphilis) antibodies detected. It can be Non-Reactive in early stages (false neg) despite Sx. GL ...Read more
Many different names: I believe that you are referring to an arthritis that is occurring in a juvenile that is negative for rheumatoid factor test- a test for rheumatoid arthritis seen more in adults. This currently is called juvenile idiopathic arthritis while it used to be called juvenile rheumatoid arthritis factor negative. There are many different types or subcategories of this as this arthritis. ...Read moreSee 1 more doctor answer
No infectious cause!: It means there is no infectious cause. Nonethless, it is almost certainly not rheumatoid arthritis in children, but what is now called juvenile idiopathic arthritis. This need not be crippling, and most can lead a perfectly normal life, including sports, with medications available. ...Read more
No syphilis.: Vdrl (veneral disease research laboratory) is a non-treponemal specific blood test that is widely used to screen populations for syphilis. A negative test if reassuring; a positive (reactive) test has to be followed by a treponemal-specific test such a fluorescent treponemal antibody absorption (fta-abs). ...Read more
My friend who is 27 years old, got the HIV test done and the report says HIV : non reactive. What does it mean?
Depends: I would want to know the following information: are they hepatitis b surface antigen reactive? Are they hepatitis b e antibody reactive? Did this person likely get hepatitis b as a baby or small child or when they were older? What is the hepatitis b dna (viral load) level? What is the alt (liver enzyme) value? In isolation this lab value can mean multiple things. ...Read more
If you are hepatitis b reactive, and then you are test again for HBsAG and the result is non reactive what does it mean? You don't have hbv?
Reactive to what?: Hbv markers are used to distinguish actively infected from immunity, the latter include antibody to surface antigen (hbsab) and to the core antigen (hbcab). Some tests detect part of the virus, such as surface antigen (hbsag), the core antigen, or hbv dna. The presence of hbsag indicates that the person is potentially infectious. Hbsab replaces hbsag as the hbv infection evolves to immunity. ...Read more
My RPR was Postive with titer 1:1 for syphilis but my FTA-ABS was Non Reactive. What does that mean? Im being treated.

I got tested to see if I was immune to Measles mumps and rubella and results: measles and rubella reactive. Mumps non reactive. What does that mean?
Need a booster shot: That result usually means the patient is immune to measles and to rubella, but is not immune to mumps. If she had her MMR shot before, her mumps antibodies are no longer high enough to ensure protection against mumps. She can ask her doctor about getting an MMR booster shot, which would increase her antibodies to block all 3 contagious diseases. ...Read more
Hb core ab-igm non reactive hepatitis b core ab total reactive and hep b surface antigen non reactive what does this mean?
I had blood tests done and my hepatitis b surface antibody QL reactive, hepatitis b surface antigen non-reactive, what does it mean?
Need entire panel.: You're best off using HealthTap Prime to answer your question. You can upload the entire lab report & discuss with a doctor. So far, test shows you have antibodies but no antigen: means either you're in the "window period" after exposure when the virus goes "underground" or you were given a vaccine which made you immune to hepatitis B. We need the pre-core "e" test. Use HealthTap Prime to disucss. ...Read more
My son is HBsAg- reactive. Anti HBs is non reactive. HBeAG is non reactive. Anti HBe is reactive. Anti HBc IgM is non reactive. what does it mean?
What to do if I have hb surface antibody as reactive(3158) but hb surf. antibody as non reactive. what doe that means.?
What do you suggest if I have hb surface antibody as reactive(3158) but hb surf. Antibody as non reactive. What doe that means.?
Inconsistent info: The information you provided does not add up. All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that and you should consult your doctor who has more information about your health. ...Read moreSee 1 more doctor answer
Hi sir, i test HIV the result shows non reactive (0.05) it means. I sex last 5 months back. What is the result means why it shows 0.05?
It means nothing: Consider it a negative test.Get a more detailed answer ›
What does it mean if I'm non reactive for hepc and the HCV signal to cutoff: 0.4 what does that mean Why is it 0.4 if I'm nonreactive wouldn't it be 0?
No: This is the nature of immunoassays. It's not counting sheep in a pasture; it's 21st century deep electronic technology stuff. And I'll admit it's often confusing. There's background noise that produces the 0.4. Best wishes. ...Read more
Infection/Autoimmune: A reactive or positive VDRL test can occur in either active infection from syphilis or from the presence of an antibody that promotes clotting blood too readily. This latter consideration arises with so-called anti-phospholipid antibodies which may arise in autoimmune disease. One of these autoimmune diseases is lupus or "SLE" (systemic lupus erythematosus). Syphilis would not be the cause here. ...Read more
