A Guide to Multi-Target Diagnostics for Point-of-Care Applications

The increasing adoption of multiplex point-of-care (POC) tests is reshaping diagnostics. By 2029, it’s projected that the global market for multiplex diagnostics will exceed $42 billion, growing at a compound annual growth rate (CAGR) of 16.2% from 2023. This growth underscores the burgeoning demand for efficient, cost-effective, and highly precise medical testing.

Let’s delve deeper into how multiplex diagnostics function and how they are facilitating the rapid identification of various diseases from a single patient sample using advanced technologies.

What Are Multiplex Tests?

Multiplex diagnostics are advanced medical tests capable of detecting and analyzing multiple biomarkers in a single assay. These tests enable a comprehensive assessment of a patient’s health in one go, thereby supporting more informed decision-making in clinical settings.

This approach contrasts sharply with traditional singleplex tests, which target only one biomarker at a time. For example, our standard test for a specific respiratory virus at Cost Plus Med Tech, similar to the COVID-19 Ag Test, targets only one analyte. On the other hand, our multiplex diagnostics can assess multiple analytes simultaneously. The Cost Plus Med Tech FastResponse Flu A/B & COVID-19 Multiplex Rapid Test distinguishes between antigens from both influenza strains and SARS-CoV-2, all from a single nasal swab, delivering results in just 10 minutes.

Primary Applications of Multi-Target Diagnostics

The utility of multiplex diagnostics spans numerous medical fields:

  • Infectious Diseases: These tests are crucial for identifying multiple pathogens in diseases such as COVID-19 and influenza.
  • Cancer Diagnostics: By detecting various cancer-specific biomarkers, these tests facilitate more accurate diagnosis and monitoring.
  • Chronic Conditions: They are also used in diagnosing and managing autoimmune diseases, cardiovascular issues, and neurological disorders.
  • Genetic Screening: Multiplex tests are effective for identifying genetic disorders and susceptibilities to certain conditions.

Key Technologies in Multiplex Diagnostics

Multiplex diagnostics employ various technologies based on the analyte and testing requirements:

Molecular Assays

This category includes techniques like polymerase chain reaction (PCR), which amplifies DNA sequences to detect specific pathogens or genetic markers. While highly sensitive, PCR tests can sometimes detect remnants of old infections, indicating a positive result where there is no current infection.


These involve antibodies that bind to target molecules, often used due to their rapid processing times. The Cost Plus Med Tech FastResponse test, for instance, is a lateral flow immunoassay, capable of quickly identifying specific proteins or antigens.

Operational Steps in Multiplex Immunoassays

Here’s a brief overview of how multiplex immunoassays work at the point of care:

  1. Activating Capture Molecules: These tests begin by fixing specific antibodies to a solid surface, each linked to a different target molecule.
  2. Sample Incubation: The patient’s sample is added and allowed to incubate, binding to the immobilized antibodies.
  3. Target Detection: Detection molecules then bind to the target-antibody complex, generating a measurable signal.
  4. Signal Measurement: The intensity of this signal indicates the concentration of the target analyte within the sample, thus providing diagnostic information.
