Generally

Rapid and reliable diagnosis of pharyngitis with QuikRead go Strep A

Sore throat (acute pharyngitis) is one of the most common reasons for seeking medical attention in primary care.1 When a patient presents with a sore throat (acute pharyngitis), it can be difficult to differentiate, based on visual inspection only, whether the infection is caused by Strep A or by viruses.

QuikRead go Strep A

QuikRead go Strep A is a simple qualitative test for the detection of Strep A in a throat sample in pharyngitis patients. It provides quick and accurate results during consultation, identifying those patients who need treatment with antibiotics. Test result is distinctively displayed on QuikRead go instrument eliminating the uncertainty and subjectivity associated with the Strep A tests that require visual interpretation.

Fast and objective results

  • Minimal hands-on time
  • Analysis time less than 4 minutes, 2 minutes for clear positive or negative samples
  • Storage at room temperature up to +25 °C

Effortless testing with the QuikRead go multianalyte instrument

  • Ready-to-use reagents
  • Fully automated measurement
  • Maintenance free
  • Battery use ensures full portability
  • Bi-directional connectivity to most HIS and LIS systems

Test results should never be used alone, without a complete clinical evaluation. QuikRead go Strep A is not registered in the USA.

About Streptococcus pyogenes (Strep A)

Acute pharyngitis is one of the most common reasons for seeking medical attention in primary care. Most cases of acute pharyngitis are caused by viruses. The most common bacterial cause is Streptococcus pyogenes, also known as Strep A. Strep A infection is the only commonly occurring form of sore throat warranting antibiotic treatment. As the signs and symptoms of Strep A infection and those of pharyngitis caused by other micro-organisms (mostly viruses) often overlap, it is difficult to rule out Strep A infection on clinical grounds alone.

Although most cases of sore throat are benign and self-limiting, infections caused by Streptococcus pyogenes, Strep A, require antibiotic treatment.

Specific features of sore throat and Strep A

  • Sore throat is usually due to an inflammatory response to viral or bacterial infection.
  • Most cases of sore throat are caused by viruses.
  • Of bacteria, Strep A is the most likely causative organism.
  • Strep A sore throat affects mainly children and young adults.
  • Symptoms of Strep A infection and those caused by other micro-organisms often overlap.
  • Antibiotic therapy reduces the duration of symptoms.
  • The amount of antibiotic prescriptions due to Strep A sore throat exceeds by far the expected prevalence of this infection.

As the signs and symptoms of Strep A infection and those of pharyngitis caused by other micro-organisms (most commonly viral) often overlap, it is difficult to make an diagnosis on clinical grounds only.
To avoid inappropriate antibiotic treatment of large numbers of patients with pharyngitis, it is important to verify or exclude Strep A infection. The diagnosis should be based on clinical and epidemiological data supported by laboratory tests.

Use of throat sample culture is an accurate and sensitive diagnostic way for finding out if Strep A is the cause for pharyngitis. The culture, however, takes time and the result is available only next day. Strep A rapid antigen tests are easy to use and reliable enough for primary care use to support the decision to prescribe antibiotics while the patient is at the doctor.

Frequently asked questions

Are the results affected if I do not use the swab intended for the QuikRead go Strep A kit?

Yes. It is very important to use the swabs intended for the kit as other types of swab may cause false results. Some swabs contain substances which may inhibit the reaction and cause false negative results, whereas other swabs may affect the buffer volume causing either a false positive or negative result.

Why do I have to observe the colour changes during the extraction and after adding the sample into the prefilled cuvette?

The Extraction Reagent 2 contains a pH indicator which helps you to ensure that the test procedure is correct. The extraction solution must be acidic (yellow-orange colour) and the acid has to be neutralised (pink) by the buffer in the cuvette before addition of the reagent.

Do I have to update the QuikRead go Instrument software to be able to use the QuikRead go Strep A kit?

The QuikRead go Strep A kit can be used in QuikRead go Instruments with software version 4.1 or later.

Is it possible to order extra swabs for the test?

HydraFlock swabs are available in a pouch including 50 single packed swabs.
Each swab is CE-marked (MDD 93/42/EEC) and the product can be delivered to the European Economic Area (EEA) countries. The product number for the HydraFlock sterile flocked collection devices to be used with QuikRead go Strep A swab pouch is 153212.
