New crown nucleic acid rapid test is a precise experimental process, and the result it produces is often a more accurate result. So, how does it manage to determine that the results reported by the long-running New Crown Nucleic Acid Rapid Test instrument are accurate?

A very important aspect of this is the "quality control product".

When the collected nucleic acid samples are transferred to the New Crown Nucleic Acid Rapid Test laboratory, New Crown Nucleic Acid Rapid Test personnel need to go through a series of steps such as sample reception, nucleic acid extraction, nucleic acid amplification, and result analysis to turn the received samples into the final result report. The quality of the New Crown Nucleic Acid Rapid Test is particularly important for epidemic prevention and control, and the New Crown Nucleic Acid Rapid Test quality control products are an essential part of quality assurance.

What is a QC for Nucleic Acid Rapid Test?

QC, as the name suggests, is an item for quality control in the experimental process, which can be used for test system performance verification, indoor quality control and inter-room quality evaluation, etc. QC: is a stable substance used to check the performance of analytical instruments or methods. Its analytical properties are similar to those of patient samples and is used to check the performance of analytical instruments or methods. In layman's terms, a QC is a control, which is equivalent to a sample in the assay.

Generally there will be negative QCs and positive QCs, with negative QCs testing negative and positive QCs testing positive. Negative QC can exclude false positive results caused by reagent or environmental contamination; positive QC can monitor the performance of reagents or personnel operation is normal, used to exclude false negative results. QCs should be randomly placed in clinical specimens to participate in the whole process from extraction to amplification.

So how do we determine if a QC result is under control?

First, we need to understand that a QC is equivalent to a sample in an experiment. One is the absolute negative sample, and the other is the absolute positive sample. Then we have to monitor the indicators of the two "samples" in the experiment. When the positive QC result is not positive, we should consider whether there is a problem with the instrument, and when the negative QC test is positive, we need to pay attention to the contamination problem.

So does the New Crown Nucleic Acid Rapid Test System require QC?

Like conventional testing systems, the New Crown Nucleic Acid Rapid Test System requires QC testing. According to the "Notice on further strengthening the work of fever outpatient nucleic acid testing of the new coronavirus" (Shanghai health medical letter

[2021] No. 181): the laboratory using the new coronavirus rapid reagents and supporting equipment to carry out testing, should be weakly positive and negative quality control each time the machine is turned on, and after the number of consecutive monitoring specimens reaches 50 or the machine is turned on for 24 hours, it should be weakly positive quality control product quality control again. Because of the new crown nucleic acid rapid test system throughput is generally small, so will not add quality control products for each batch of samples, but also can not do without quality control, so in the use of the rapid test system, we have to carry out a certain number of samples after the new crown nucleic acid rapid test and instrumentation up to 24 hours to carry out quality control with the test.

Although not always quality control, but the new crown nucleic acid rapid test system has its unique advantages, compared to conventional testing, the new crown nucleic acid rapid test detection efficiency is faster, and smaller, can be more suitable for the new crown test mobile cabin, airport, customs, fever clinic laboratory a variety of scenarios.
