New Covid 19 Testing - Dr Emma Hayhurst Interview Part 1

Dr. Emma Hayhurst, a senior lecturer in microbiology, explains a molecular test that uses a throat or nose swab. The test operates at a constant temperature of 65°C and provides results in 20 minutes, unlike PCR which takes longer. This test is faster due to its unique reaction process and requires less sample processing. It also circumvents the global reagent bottleneck by using different chemicals. The test, based on LAMP technology, is more accurate and specific than PCR, using six primers instead of two.

What is the primary purpose of heating the sample to 65 degrees in the molecular test?

• To sterilize the sample

• To detect nucleic acid sequences

• To change the color of the sample

• To separate the DNA strands

Why is the molecular test faster than traditional PCR tests?

• It uses a different molecular reaction

• It requires more sample processing

• It involves more temperature cycling

• It uses the same chemical mixture

What is one advantage of the molecular test over PCR in terms of chemical reagents?

• It uses less accurate reagents

• It uses the same reagents as PCR

• It avoids the global bottleneck of chemical reagents

• It requires more reagents

How many primers does the molecular test use for detection?

• Six

• Two

• Four

• Eight

In what way is the molecular test potentially more accurate than PCR?

• It uses fewer primers

• It uses more primers

• It is less specific

• It requires less sample
