Because current tests don't do an adequate job of identifying antibodies resulting from immunization, the CDC does not recommend post-vaccine titers for anyone, including health care workers. So, at this time, the answer to your question is "never."
You appear to be confused about the nature of shingles. A positive varicella titer shows that you have had chickenpox in the past, or that you have had the vaccine for chickenpox. You can't get shingles unless you've had chickenpox. If you have had chickenpox, a positive varicella titer is not protective against shingles, and you may need the vaccine. Discuss with your health care provider whether shingles vaccine makes sense for you.
At this time, only two chickenpox vaccines are recommended in the series. A third vaccine isn't not recommended, even if the varicella titer indicates no reaction or insufficient titer levels. See related link for references.Another answer:Not all will be immune with two doses. A low titer may require a third dose.
a blood test to determine if you have immnuity to varicella (chicken pox).
Yes, as long as you have demonstrated immunity to chickenpox, you can go to work in a medical environment if your son has chickenpox. If you have had chickenpox or shingles diagnosed in the past; if you have had chickenpox vaccine; or if you have had a titer demonstrating immunity, there is no risk. Talk to the infection control department or contact at your facility for details specific to your situation.
Natural immunity to chickenpox results from previous infection. There is no other way to be naturally immune to chickenpox. Sometimes, the previous infection may be mild enough that the disease was not noticed. You can become artificially immune to chickenpox by getting chickenpox vaccine.
It means you're immune to chickenpox.
There is no "chickenpox procedure." There is a diagnosis code for chickenpox, but no CPT code. There are CPT codes for chickenpox titer, culture, and immunization.
People who have chickenpox normally develop immunity that lasts throughout their life, and they are unlikely to get chickenpox a second time. It is possible for a person who had chickenpox earlier to get shingles, a related disease that affects between one fifth and one third of those who had chickenpox earlier.
Yes, you can get a blood test to check your titer (immunity level) for measles, chickenpox, and rubella (German measles).
It means that they tested for the vaccine in your body and it tested positive aka, vaccine is already inside you. No need for another
Typically, a rubella titer is done before the first pregnancy. Chickenpox titer may be done at this time, also. Sometimes these tests are required before getting certain types of work. It is not necessary to get these tests repeated; once is enough.
Yes, you can go to your doctor and they can test your blood to see if you have the antibodies or not. The test is a varicella titer, or varicella IgG.
