If you had Rubella in the past but your blood test shows a negative result, it could indicate that your body has not developed antibodies to the virus, which may happen if the infection was mild or not fully resolved. It's also possible for the test to be a false negative. If you're concerned about your immunity or potential for future infections, it's advisable to consult a healthcare professional for further evaluation and potential vaccination options.
According to a Yahoo! Health article (http://health.yahoo.com/infectiousdisease-diagnosis/rubella-test/healthwise--hw5576.html):A rubella blood test detects antibodies that are made by the immune system to help kill the rubella virus. These antibodies remain in the bloodstream for years. The presence of certain antibodies indicates a recent infection, a past infection, or that you have been vaccinated against the disease.The presence of IgM antibodies means you have a current or recent rubella infection.The presence of IgG antibodies means you have immunity against the infection. This immunity could have been received either through vaccination for rubella or a past rubella infection.As long as the IgM test is negative, both you and your baby are in the clear!

Whether you have Rh Negative blood or Rh Positive blood has nothing to do with getting a TB test. TB testing should be done at least once a year which will show whether or not you have been exposed to Tuberculosis.
Doctors determine positive or negative blood types by testing for the presence or absence of a specific protein called the Rh factor on the surface of red blood cells. A positive blood type indicates the presence of this protein, while a negative blood type indicates its absence. This information is important for blood transfusions and pregnancy monitoring.
