AOAC 2017.01 Viral Pathogen Rapid Detection in Clinical Samples
The AOAC 2017.01 standard method provides a rapid, accurate, and reliable means of detecting viral pathogens directly from clinical samples. This method is particularly valuable for identifying the presence or absence of specific viruses in patient specimens, which is critical for timely diagnosis and treatment decisions.
This service focuses on the direct detection of viral nucleic acids using quantitative real-time polymerase chain reaction (qPCR). The protocol aims to minimize the time required from sample collection to obtaining results, ensuring that healthcare providers can make informed decisions promptly. The AOAC 2017.01 method is compatible with a wide range of clinical specimens including blood, urine, nasopharyngeal swabs, and other body fluids.
The testing procedure begins by collecting the sample into a suitable container. Once received at our laboratory, the sample undergoes rigorous quality control checks to ensure integrity before proceeding to nucleic acid extraction. This step is crucial as it ensures that the extracted DNA or RNA is free from contaminants which could lead to false positives.
Following extraction, qPCR reagents are added to the samples in preparation for amplification. During this process, primers and probes specific to the target virus sequences are used to amplify minute quantities of viral nucleic acids present in the sample. The amplified products are then analyzed using fluorescent detection technology incorporated into real-time PCR machines.
Our laboratory employs state-of-the-art instruments such as ABI 7500 Fast Real-Time PCR System, which allows for high sensitivity and specificity in detecting even small amounts of viral nucleic acids within clinical samples.
The resulting amplification data is analyzed using dedicated software that calculates cycle threshold (Ct) values indicative of the initial concentration of target DNA or RNA. Lower Ct values suggest higher concentrations of the targeted virus, while higher values indicate lower levels or absence of the virus in question.
Our AOAC 2017.01 service guarantees accuracy and precision by adhering strictly to all guidelines set forth by this international standard. This ensures that our results are both reproducible across multiple runs and consistent with those obtained at other accredited laboratories performing similar tests.
In addition, we provide detailed reports outlining the specific viral species detected along with their respective Ct values. These reports serve as valuable tools for healthcare professionals in diagnosing infections caused by these pathogens effectively.
By offering this service, our laboratory aims to contribute significantly towards enhancing public health outcomes through rapid identification of potentially harmful viruses early on during an outbreak or individual case.
