NeoDx Assay Development:
Ensuring Accurate Results

At NeoDx Biotech Labs, developing an in-Vitro Diagnostic kit or an assay development project is backed by years of experience and an expert team of scientists. We have developed and manufactured kits that are in use by diagnostic centers across India.

Whether you want to develop a Lateral Flow Assay based Product or a Real Time PCR based Diagnostic Kit, our products include high-performance formulations ensuring a quicker path to commercialization. 


We follow Phase-gated and regulated processes for developing products.

Lateral Flow Assay (LFA), also known as Lateral flow immunochromatographic Assay (LFIA) or a Lateral Flow Device (LFD), is widely used as a point of care device/Point of care test (PoCT/PoCD). 


LFAs help in visually confirming the presence or absence of a target analyte (for example Biomarkers, hormones, or pathogens) in the liquid sample. LFAs that have an antigen as a target analyte is generally referred to as Rapid Antigen Tests or RATs.


As a PoCT/PoCD, Lateral Flow Assays eliminate the need for costly and specialized equipment; and can provide results in under thirty minutes making them simple and economical.

Real Time Polymerase Chain Reaction, is a molecular biology technique that monitors the amplification of a targeted DNA Molecule in real-time (during a PCR run) and not at its end (as in conventional PCR). 


Generally abbreviated as RT-PCR, Real Time PCR finds applications in both diagnostic and research. In Diagnostics, Real-time PCR is used to rapidly detect nucleic acids that are of diagnostic value, for instance, for the detection of infectious diseases, cancer, or genetic abnormalities. 


The application of Real-time PCR has fundamentally changed the diagnostic landscape and is considered to be the “Gold Standard” in disease diagnostics, and is employed as a tool to detect existing as well as emerging diseases like the Coronavirus (SARS-CoV-2).

At NeoDx Biotech Labs, we simplify the Assay Development process for Lateral Flow Assays (LFA) and Real Time PCR kits for In-Vitro Diagnostics.
