Please i would like to know if schistosoma ab IgG test detects every type of schistosoma ?

Mostly, yes.: This flourescent microscopy assay uses the microsomal fraction of adult s. Mansoni worms (mama) as antigen, and is thus highly specific (99%) and sensitive (96%) for detection of infection caused by s. Mansoni. Although the assay is also highly specific for infections caused by other schistosoma species (s. Japonicum, s. Haematobium, s. Mekongi), its sensitivity for these infections is lower (55%). ...Read more

HSV 2: You cannot differentiate between hsv types 1 and 2 using antibody testing because of the high frequency of cross-reactivity. The only sure way to do this is to isolate the virus from active lesions and test the virus for serotypes. This is fairly sophisticated, but imagine most large medical schools in india may have a lab that can do this. ...Read more

Tested positive on IgG Elisa for hsv2. Then tested negative on western blot 2 years after last encounter. Which test to believe ?

Tested positive on IgG Elisa for hsv2. Then tested negative on western blot 2 years after last encounter. Which test to believe ?

Western blot: The ELISA screening test is sensitive with a smaller number of false negatives which makes a good screening test. That way fewer true positives are missed. The Western Blot is more specific meaning a smaller number of false positives. A specific test misses few true negatives. It is done for confirmation. You can always repeat the tests in case of specimen mix-up (which I have seen happen before. ...Read more

Does the western blot trump the elisa? Tested positive via ELISA IgG for hsv2,but later tested negative via western blot. No symptoms. Do I have hsv2?

Western blot more: specific, ELISA more sensitive. One positive ELISA and one negative Western blot says that you do not have enough antibodies to HSV 2 for confirmation of diagnosis. It may be prudent to repeat the tests in 3-4 months to make sure that negative Western blot was not due to incomplete/early immune response. ...Read more

What happens if "h. pylori IgG antibodies serum by ELISA positive"?

What happens if "h. pylori IgG antibodies serum by ELISA positive"?

H. pylori infection: .. which causes gastritis with symptoms of early satiety, abdominal pain, heartburn. If you are symptomatic, then you will need the treatment. If you are not symptomatic or have responded to treatment already, then your test result indicates ongoing antibody production (normal immune response to previous infection) and no treatment is required. Good luck! ...Read more
