Sample processing for drug resistance testing
It is critical to have a comprehensive sample tracking system and a consistent laboratory procedure to ensure the integrity of processed samples.
CFAR LABS provides custom DNA| RNA extraction techniques from a variety of samples, such as a whole blood, plasma, CSF, and other body fluids and tissues.
Our dedicated laboratory analysts and quality assurance personnel always ensure that the highest expectation is met.
In case of WHOLE BLOOD; the sample should be in an EDTA tube (purple top vacutainer tube) well labeled with an identifier that is unique to the facility that is requesting the service. At least 4ml of whole blood should be sent to the lab
In case of PLASMA; this should be brought to the lab right away, if fresh, it should be brought at room temperature but if it was taken off some time back, plasma sample strictly has to be kept frozen at -80 degree Celsius and has to be brought in a frozen state and well labeled. Volume should be 1.5 to 2ml.
In case of CSF, the sample should be brought to the laboratory straight away after it has been taken off from the patient. Otherwise, it should be kept at -20 c; then brought to the laboratory on cold.
In case of PBMCs; these should be brought to the laboratory on cold packs (for DNA extraction).
Patient sample information
The following information has to be included:
- Patient drug regimen should be given or specifying which HIV virus region to be worked upon; reverse transcriptase (RT), protease (PR), intergrase (INT) regions, coreceptor antagonists
- Most recent viral load test result (for amplification procedure, we require a viral load of 1000 or more copies per ml.)
- Date of sample collection
For the convenience of our customer, CFAR LABS offers banking services of the extracted DNA|RNA samples incase further analysis is required. Our ultra-low temperature freezers are kept in a controlled access and are monitored at all times.
The banking services is also offered to customers who are interested in using our facility as primary or back up repository of their genetically modified microbial isolates or eukaryotic cell lines.
The template for your order is automatically be stored for 2 weeks. Long term storage services are offered to those who are planning to use templates in future.
We also offer primer banking for those who need it. This is for convenience of our customers. The primer for your order will automatically be stored for 2 weeks. We offer free primer storage services for those who are planning to use them in future.
