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!

You took a home pregnancy test it came out negative however the negative line is still there and you took it 2 hours ago The directions said that If negative it shouldnt be able to be read after 10 mi?

On a test, there are usually two lines. The one line is what you call the negative line and shows up if you have a negative or a positive result. A test is positive only if two lines show up. The negative line usually stays. The ten minute reference means that the test results after ten minutes will not be reliable. If the result is negative in the first minutes, then that is your proper result.
