Multiplex testing: What is it?

Multiplexed Point-of-Care Testing (xPOCT), also known as a multiplex test, is the simultaneous on-site assessment of numerous chemicals from a single sample. The intelligent coupling of a high-performing device with minimal system complexity is the main goal for the development of systems for the multiplex test. This ensures that the on-site tests are carried out quickly by non-experts and that the results match those from clinical settings and centralised laboratories.

Importance of Multiplexed Points of Care Testing (xPOCT)

For an illness to be effectively treated, an early, precise and multiplex test needs to be developed. This test should be able to prepare multiple assays and provide faster results, particularly at the point of care, where a prompt treatment choice is most necessary. Clinical evidence based on a single biomarker, however, is insufficient to properly diagnose a disease or to track its course through treatment. In light of this, multiplexing has grown in significance for point-of-care testing over the past ten years.

Ideal Qualities or Characteristics of Multiplexed Point of Care Testing Device:

Diagnostic instruments must meticulously carry out the following duties to adequately meet the requirements for xPOCT:

1. Little sample consumption or the availability of non-invasive (easily accessible) samples like urine, sweat, and breath condensate;

2. System operation that is straightforward or automatic and requires little user involvement;

3. Quick turnaround times (between 10 minutes and 2 hours), which enable urgent treatment;

4. Extended shelf life and storage of reagents;

5. Quantitative data that are accurate and in line with clinical and core laboratory findings;

6. Readout devices that are inexpensive and portable and come with disposable test strips or cartridges;

7. In the developing world, equipment-free or mobile phone-based systems are strongly desired;

8. The xPOCT gadget should also have the ability to evaluate multiple chemicals at once, such as RNAs, metabolites, proteins, exosomes, and cells.

Current xPOCT Approach The method primarily tries to employ a single or small set of biological samples to split or separate them so that they can be read by several types of assays. multi-analyte detection or Multiplex-Testing is often performed using three primary approaches.

1. Regional separation using different electrode or channel network parts

2. Geographical separation of detecting sites using different wells or places

3. Use of several labels, including enzymes, redox compounds, beads, and colours.

4.Other point of care lab testing directly identify biomarkers using mass spectrometry (MS). But the majority of these technology-based devices are cumbersome and challenging to use. Optical and electrochemical detection techniques are mostly used for the signal readout.

Modern xPOCT Technologies

The following categories of diagnostic tools are now in use for multiplex tests:

• Paper-based systems: Lateral flow assays, such as those used in pregnancy tests, use samples that react with coloured particles and call for the device to read the colour signature.

• Array-based systems - Instruments that contain fluorescent molecules or electrodes and are sensitive to particular analytes

• Bead-based systems - Systems, such as bead-based flow cytometry, use beads as a medium for the analytes to bind precisely to before those complexes are then filtered or separated by size or colour.

These advancements have opened various unthinkable opportunities for doctors to serve humanity.

 Multiplex testing is also one of the most remarkable diagnosis methods.  Yes, you guessed it right. The name is taken because of its similarity with a multi-screen cinema complex aka Multiplex. The key feature of multiplex tests is that it allows you to take multiple tests of the same person at the same time.Hence the name ‘Multiplex’.

 What is the multiplex test?

If you try to understand it in simple words, the multiplex test is the process of combining many signals into one channel. It is a type of immunoassay. The multiplex test is the diagnosis method in which multiple tests are conducted simultaneously on a single sample. The disorders like an autoimmune disorder, infectious diseases, allergies, toxicology, and genetically inherited diseases can be treated through this test.

 This test uses flow cytometry technology to do multiple tests with accuracy. This test uses magnetic beds to measure multiple analytics in a single experiment. The process is such that the microspheres of designated colours are coated with specific antibodies. After the fluorescent signature, the analytics are measured by the number of different bead colours.

 How the multiplex test will be beneficial to you?

Because of the variety of benefits that come along, Multiplex is becoming very popular. There are several ways in which multiplex test can benefit you:

 ·         Pocket friendly:

One of the major benefits of the multiplex test is that it is cost-effective. The package of the test combines more than 10 different tests related to different disorders &diseases. If one opts for testing separately for each taste,it will cost much higher comparatively.

 ·         Higher accuracy:

The multiplex test involves high speed and advanced technologies that yieldaccurate results. It conducts every individual test eliminating the effect of various multiple testing factors like timing, condition, methods, and results.

 ·         Less pipetting errors:

Multiplex testimproves precision by minimizing pipetting errors. In this method, fewer pipetting errors occur because of its segmented procedure. As complicated as it may sound, the method incorporates measures & precautionsto avoid pipetting errors.

 ·         Optimized resource requirements:

Separately testing for different purposes may require a lot of resources such as plates, wells etc. On the other hand, Multiplex Test requires very input materials as compared to others. This is also one of the many reasons why these tests are cost-effective.

 ·         Low risk of contamination:

The procedure of multiplex testing is such that it is performed in a closed set-up.

Therefore it decreases the possibility of contamination. The proper measure to maintain hygiene is taken care of. This test is safer than others.

 ·         More throughput:

Throughputs are identifying a higher number and samples in a day. The process of multiplex test process offers an increased rate of throughputsand thus resulting in reduced costs per sample.

 ·         More information with fewer samples:

Multiplex test targets more than 10 pathogens in a single test sample. This test determines the cause of diseases and also suggests appropriate drugs for them. It tests for all disorders in shotgun fashion, rather than hypothesis.

Separating the individual assays into different spaces (spatial separation) or immobilising antibodies onto different beads based on what they target are the two main ways to multiplex test an immunoassay.

Multiplex test PCR necessitates two or more pairs of primers in the reaction, allowing for the amplification of multiple genes in a single reaction. A single test run may provide additional information that would otherwise require multiple reagents and more time to complete. Multiplex-PCR can be used to detect different serotypes of Shiga toxin-producing bacteria, for example.

 Why use a multiplex assay?

Of course, the main benefit of a multiplex assay is that it allows you to analyze multiple proteins at once rather than having to run multiple assays to look for each protein individually.

Running different assays means there may be minor differences in each run, which could affect the results. Running a single assay prevents this variation from having a major impact, so any differences in protein levels are more likely to represent true relative abundance inside the samples.

Advantages of multiplexing

 By measuring the expression of more than one gene in a qPCR reaction with a multiplex test, you can minimize the amount of sample needed for a qPCR reaction. The method is as delicate and precise as single-gene amplified (also known as singleplex), but it is more technically difficult.

Multiplexing has other benefits in addition to conserving the amount of precious samples. The first is a cost-cutting strategy. When you amplify two or more genes in the same well, you save money on reagents and time spent setting up experiments and analysing results.

Second, multiple gene amplification in the same well increases accuracy by reducing pipetting errors. Small differences in sample and reagent quantities in each well will not cause problems if the genes to be compared are amplified in the same wells.
