People with blood cancers  such as leukemia, lymphoma, and myeloma - often lack antibody-making immune cells called B cells, particularly after treatment with certain medications. If a pool tests positive, scientists then re-test smaller groups of samples included in the pool in order to find the positive one. A study published on Tuesday in PLoS Medicine suggests that boosting vitamin D levels with supplements would not help. But among the blood cancer patients, those with higher levels of CD8 T cells were more than three times more likely to survive than those with lower levels of CD8 T cells. However, they found a massive gap between primary transmitters who were symptomatic and those who were asymptomatic.
People with blood cancer  tested positive for an anti-pool study.
