Test systems are available in our clinic to diagnose coronavirus infection, including Omicron and Delta strains.
Preparing for the test
- It is not recommended to use medications for irrigation of the oropharynx, nasal lavage and drugs for resorption six hours before the examination.
- Also it is not recommended to eat, brush your teeth, smoke and use chewing gum for three to four hours before the examination.
- It is recommended to blow your nose if there is a discharge in the nasal passages before the examination
- Detection of SARS-CoV-2 coronavirus RNA by real-time PCR, qualitative test. Material for the study is nasopharyngeal mucosa (swab) / oropharynx.
Ready in 12-24 hours if the material is collected before 8 pm.
Analytical sensitivity: 5*10³ HE/ml.
Interpretation of the result
«Not detected» — no RNA fragments specific for SARS-CoV-2 coronavirus are present in the biomaterial, or RNA concentration in the biomaterial is less than the sensitivity limit of the test.
«Detected» —RNA fragment specific for SARS-CoV-2 coronavirus presents in the biomaterial.
A negative result on the initial test is given immediately. Confirmatory test is repeated, if a positive or questionable result is obtained.
- Detection of SARS-CoV-2 coronavirus RNA by real-time isothermal amplification method (LAMP), qualitative test. Material for the study is nasopharyngeal mucosa (swab) / oropharynx.
Quality: 12-24 hours if material is taken before 8:00 pm.
Analytical sensitivity: 5*10³ HE/ml.
AmpliTest SARS-CoV-2 LAMP reagent (CSP) on the CFX96 instrument (Bio-Rad).
Interpretation of the result
«Not detected» — there are no RNA fragments specific for SARS-CoV-2 coronavirus in the biomaterial, or the RNA concentration in the biomaterial is less than the sensitivity limit of the test.
«Detected» — RNA fragment specific for SARS-CoV-2 coronavirus is present in the biomaterial.
A negative result on the initial test is given immediately. Confirmatory test is repeated, if a positive or questionable result is obtained.
-
Detection of RNA variants Omicron and Delta of SARS-CoV-2 coronavirus using test-system «AmpliTest® SARS-CoV-2 VOC v.3», a qualitative test produced by FSBI «CSP» FMBA of Russia. Material for the study is the separation of nasopharyngeal mucosa (swab) / oropharynx.
Ready in 24-36 hours (+ 1 day if a positive / doubtful result of the primary study).
Analytical sensitivity: 10³ HE/ml.
Negative results of the primary study are given immediately. In case of a positive or questionable result there is a repeat confirmation study using a set of reagents produced by FSBI «CSP» Federal Medical and Biological Agency of Russia "AmpliTest ® SARS-CoV-2 VOC v.3.
Result Interpretation
Primary result:
«Not Detected» — there are no RNA fragments specific to SARS-CoV-2 coronavirus in the biomaterial, or RNA concentration in the biomaterial is less than the sensitivity limit of the test.
«Detected» — RNA fragment specific for SARS-CoV-2 coronavirus is present in the biomaterial.
Options for a positive confirmatory test result:
Detected
- There is not enough RNA SARS-Cov-2 for the genetic lineage analysis.
The result says that the quality of RNA in the sample sample is not enough for detection of the particular virus strain.
- SARS-Cov-2 RNA of genetic variant DELTA and OMICRON is not detected. The result says that the strains of DELTA and OMICRON are nor detected, but typical fragment of RNA SARS-Cov-2 presents in biomaterial.
- SARS-Cov-2 markers of the OMICRON genetic variant have been identified.
- SARS-Cov-2 markers of the DELTA genetic variant have been identified.
Advantages of the test
The test allows to differentiate Delta and Omicron strains of SARS-CoV-2 coronavirus in biomaterial. Practical value of differentiated detection of Omicron strain lies in the possibility of timely anti-epidemic measures (isolation of patient, work with contact persons) in conditions of increased infectiousness (contagiousness) of this strain.
