The present invention is directed to detection and measurement of gene
transcripts and their equivalent nucleic acid products in blood.
Specifically provided is analysis performed on a drop of blood for
detecting, diagnosing and monitoring diseases using gene-specific and/or
tissue-specific primers. The present invention also describes methods by
which delineation of the sequence and/or quantitation of the expression
levels of disease-specific genes allows for an immediate and accurate
diagnostic/prognostic test for disease or to assess the effect of a
particular treatment regimen.
