Treatment of chronic myelogenous leukemia, finding the correct dose of the appropriate targeted agents after diagnosis is a condition for the best effect.
3/6/12 months after the first treatment started, a chromosome test via a bone marrow examination and quantitative BCR-ABL1 gene examination via blood will be performed.
The results of the genetic tests performed at each time point should show a gradual decrease of 10%, 1%, and 0.1%, and if the optimal curative effect is achieved, it will decrease to less than 0.1% within a year.
If treatment goes successful and a major Molecular Response is obtained, life expectancy is similar to a normal person. And if the treatment continues, the chances of obtaining less than 0.0032% of the BCR-ABL1 gene, the complete molecular response, are increased. Eventually, the chances of stopping targeted agents for a certain period will increase.

1drop's 1copy™ BCR-ABL qPCR Kit shows high precision and sensitivity in quanitative testing for CML. Capable of detecting BCR-ABL genes with high sensitivity - 0.0017% IS, the 1copy™ BCR-ABL qPCR Kit can stably detect and measure BCR-ABL1 levels at 0.0032% or lower (Complete Molecular Response). The 1copy™ BCR-ABL qPCR Kit has a short response time and is convenient,
due to its single-process reverse transcription and amplification response.

Fast and Convenient

The 1copy™ BCR-ABL qPCR Kit allows for fast and convenient use
by detecting multiple mRNA targets in a single step.
