Interpretation of COVID-19 RT PCR Positive & Negative Results on Sequential Samples

RT-PCR for SARS-CoV-2 is a diagnostic test designed for detecting the virus in respiratory samples of symptomatic individuals.

  • It is therefore very specifc, so positive results are real sensitivity however is lower and false negative results may occur in up to 20% of swabs done, especially in mild or asymptomatically infected individuals.
  • Referring doctors and patients usually have difficulty in interpreting these results, particularly when performed sequentially on patients, resulting in negative/positive or positive/negative discordances.

Non-invasive prenatal screening (NIPS)

Non-invasive prenatal screening (NIPS) is the most sensitive and specific screening test for the common foetal aneuploidies. Due to advances in genomic technologies, we can detect the presence of foetal cell-free DNA, derived from the placenta, circulating in the maternal blood to screen for common foetal aneuploidies. The preferred nomenclature changed from NIPT to NIPS ('S' for screening) to emphasise that utilising a cell-free DNA approach is a screening test and not diagnostic.
