AI Technical Summary
Poor quality management of blood samples during nucleic acid extraction leads to a decrease in the accuracy and reliability of nucleic acid analysis. In particular, the contamination of gDNA affects the detection of cfDNA, and it is difficult to guarantee the quality of testing on the day of blood collection after remote sample collection, resulting in a waste of time and resources.
By predicting and determining steps, the amount of gDNA is predicted based on the type of blood collection tube and the number of days elapsed, and the blood processing procedures are determined. Image sensors and absorbance measurements are used to confirm the blood status, optimize the nucleic acid extraction and measurement process, and reduce unnecessary nucleic acid extraction and detection steps.
It achieves accurate and rapid nucleic acid test results, reduces unnecessary nucleic acid extraction and testing steps, avoids waste of resources and time loss, and improves the accuracy and efficiency of testing.
