QUALITY GUARANTEEING METHOD IN BODY FLUID ISOLATION NUCLEIC ACID TEST

摘要

PROBLEM TO BE SOLVED: To provide a quality guaranteeing method capable of detecting abnormality even though one to a few pieces of very little quantity of cells are mixed in a plasma or serum sample.

SOLUTION: The quality guaranteeing method of the serum or plasma sample is characterized by including a step for measuring the copy number (C) in the serum or plasma sample of the predetermined quantity or the index value reflecting the same of the gene (for example, 18SrRNA) in which the copy number (A) in one cell is more than the copy number (B) in the serum or plasma sample of the predetermined quantity into which one derived from cells is not mixed and a step for comparing the copy number (C) relating to the above sample or the index number reflecting the same and the above copy number (B) or the index number reflecting the same and determining whether or not the cell including a specific gene is mixed in the sample based on the above result.
