What testing lab supplies are required for the covid nucleic acid test?
The detection accuracy of the new coronavirus nucleic acid is relatively high, because the laboratory needs to meet the following two conditions to be diagnosed as positive:
1. In the same specimen, if the real-time fluorescent RTPCR detection of both targets of the new coronavirus is positive or the detection result of a single target is positive, it needs to be re-sampled or re-tested. If it is still positive for a single target, it will be regarded as positive.
2. Positive results for a single target in real-time fluorescent RTPCR of two samples at the same time, or positive results for a single target in both nucleic acid tests of the same sample, can be judged positive.
Because the laboratory's determination standards are relatively strict, the accuracy rate is relatively high, but a negative nucleic acid test result cannot rule out new coronavirus infection, because the following factors can produce false negatives, including poor sample quality, inaccurate sample collection sites, and sample collection. False negatives can be caused by premature or late collection, failure to properly store and transport specimens, or the existence of the technique itself. Therefore, excluding the above factors, if there is a positive result, it can basically be regarded as a new type of coronavirus infection.
Yonyue can provide the following laboratory consumables
Compatible with Eppendorf ,Gilson ,Thermo Pipette
Suitable products: Deep well plate ,PCR Tube .
After autoclaving (121℃, 20 minutes), it still maintains good transparency, verticality and pipetting accuracy;
After autoclaving (121℃, 20 minutes), it still maintains good transparency, verticality and pipetting accuracy;
The filter type can effectively avoid cross-contamination between samples caused by the formation of aerosols due to the volatilization of the liquid during the pipetting process of the tip;
The low adsorption version can not only improve the recovery of precious samples, but also improve the accuracy of pipetting.
The maximum centrifugal force is 14000 RCF;
The sealing structure design of the snap cover can effectively prevent the product from being snapped or burst during the experiment operation, avoid liquid loss, and ensure the safety of the experiment;
The tube cover can be opened and closed with one hand, easy to operate;
