Question 1

what does a low antithrombin iii antigen mean?

Accepted Answer

Risk of blood clot: 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. Having said that, if the test was done correctly, it means that you are at risk for developing blood clots. You may wish to consult a hematologist for further evaluation and treatment.

Question 2

i had 3 to 4 blood clots in lungs and hospital did a test to see why i had them fibringen antithrombin iii protein c protein c antigen all high?

Accepted Answer

Not the cause of PE: Pulmonary embolism (pe) is an abnormal clot. Your docs are looking for cause. Fibrinogen is an acute phase reactant and is not likely a cause of your clot. Low protein c and low at-iii can contribute to pe; however your values are high and therefore did not contribute to your pe. I am sure your docs are looking for other causes. Good luck.

Question 3

hepatitis b antigen negative hbv load is 13160iu/ml. taking tenofo b for three months now hbv load is >20. please suggest me what can i do?

Accepted Answer

Continue to take: You are a hepatitis B virus carrier.  With the use of the antiviral agent, tenofovir, you have successfully suppressed viral replication, which will help reduce the risk of hepatitis progression.  This does not mean that you are cured however, and you will need to take this medication, as prescribed, otherwise you are at risk for viral reactivation and developing a drug resistant mutation.

Question 4

i am fully vaccinated with pfizer. i had a potential exposure three days ago. could a pcr test give me a false positive in that i fought it off but still show positive? could a rapid antigen test give me a good idea if i was positive at this point?

Accepted Answer

: A PCR test is more reliable in detecting the virus. Fully vaccinated people can get infection, however, almost always it is asymptomatic or mildly symptomatic. The person though can spread the virus to others. That is one of the reasons, CDC has advised to wear masks, even for those who are vaccinated.
Wish you good health!

Question 5

i take only one tablet of rapeprazole 20 mg then after three days i do ubt and after 6 days i do stool antigen for h pylori both tests are negative i'm afraid that this one tablet might affects the results so what is your opinion should i repeat them?

Accepted Answer

: No, rabeprazole alone could not eradicate H. Pylorii even if you take it daily before the tests.

Question 6

if i took only one pill of rapeprazole 20 mg then after three days i do urea breath test for h pylori and after five days i do stool antigen test for h pylori, both are negative and i have no complaints does the one pill affect the results ?

Accepted Answer

: Were you tested for H. Pylori before and after taking one tablet of proton pump inhibitors and positive tests changed into negative and symptoms resolved?  If it is, it is a  miracle or lab error. I am happy that you are back to good health. Thanks for sharing.

Question 7

are viruses antigens?

Accepted Answer

No: Infectious agent with nuclei acid molecule in a protein coat which has different antigens

Antigen is a protein, toxin, or foreign substance that induces an immune response in the body like production of antibodies (humoral immunity)

Question 8

are antigens and t-cells related?

Accepted Answer

T cells use antigens: Antigens are parts of large molecules, usually proteins but occasionally carbohydrates, that your immune system samples to see if they are part of your body or foreign. If foreign your immune system will try to cleanse your body of this stuff. Dendritic cells process and present antigens to t cells that in turn direct the body's immune response against the antigen.

Question 9

triple antigen prevents which diseases ?

Accepted Answer

Depends: This terminology is used more outside the US and means the combination vaccine against diptheria, tetanus and whooping cough (pertussis), given in a series of scheduled doses, followed by boosters.  There is a  triple antigen Hepatitis B vaccine (Hepacare) but this is not used in the US.  I don't know which countries offer it or even if it is still being offered.

Question 10

when does the p24 antigen peak? i heard 28 days

Accepted Answer

Yes: Normally peaks 3-4 weeks after infection.
