DeepChek®Assay INT Genotyping and Drug Resistance (HIV) (CE-IVD)

REF (122A24) (old REF K-17-H2-INT)


The DeepChek® INT Assay is intended to be used for amplifying relevant portion of the human immunodeficiency virus type one (HIV-1) integrase gene from input RNA extracted from plasma, serum or whole blood samples.

The codons spanning positions 20 to 280 of the integrase (INT) gene in the pol open reading frame are amplified.

This nucleic acid amplification method might aid in the determination of antiviral resistance in clinical samples from HIV-infected patients. The DeepChek® INT Assay is a variant of the DeepChek® PR/RT Assay.

This nucleic amplification test is indicated for use on previously diagnosed HIV patients ONLY.

This test is NOT intended to be used as a screening or confirmation test for the detection, confirmation and quantification in human specimens of markers of HIV infection (HIV 1 and 2).

Indication of Use

The amplified RNA might be used as input material in validated laboratory procedures for genomic variability testing (genotyping) potentially affecting HIV-1 susceptibility to current antiretroviral drugs including integrase inhibitors (IIs).

The DeepChek® INT Assay has been validated in laboratories for Sanger sequencing or next generation sequencing (NGS). Physicians then may use the related genotyping data in conjunction with patient clinical data to make treatment (drug therapy) decisions.

Characteristics and performances


Compatibility with Capillary Electrophoresis (SANGER) platforms

Applicable for any Sanger Sequencing technology-based instrument which can work with Big Dye Terminator v3.1 labeling (standard laboratory consumables, e.g. DeepChek® SANGER SEQUENCING REACTION V2 (24 or 48 reactions) (ABL)

Compatibility with Next Generation Sequencing platforms

Validated with iSeq100 (Illumina, USA; One-Channel SBS Chemistry, iSeq100 Flow Cell) and Illumina Sequencing Analysis Viewer (instrument software version 2.4.5) and standard laboratory consumables, e.g.ABL NGS Library Preparation kit (references 116A96 and 124A96)

Registration status

CE-IVD for European Economic Area (EEA) and countries with a mutual recognition of this conformity assessment
Research Use Only for other territories

Types of samples

Input RNA extracted from plasma, serum or whole blood samples


24 samples/kit

Covered positions

INT: codons 20 to 280


RT-PCR & Nested-PCR reagents (enzymes, master mixes, primers, dNTPs...)


1000 cp/mL


Validated on HIV-1 subtype B.
The assay is designed to detect HIV-1 subtype B but can also detect other HIV-1 Group M subtypes and recombinant viral sequences. However, as the HIV-1 genome is highly mutable, there will always be a small possibility that some strains of HIV-1 will react poorly with the assay, especially if random mutations occur within the primer binding sites.

Repeatability / Reproducibility


Median coverage

100% of samples with an optimal median coverage at a concentration of 1000 cp/mL (assay cut-off)
Median coverage per sample for the three amplicons (PR/RT and INT) was 13’237 reads (downstream sequencing with NGS)

Clinical reproducibility


Clinical sensitivity



From sample to result in ~15 hours for SANGER and ~30 hours for NGS (depending on the platform)

Compatible extraction and PCR

RNA extraction: general laboratory device (i.e. Roche MagNa Pure)
Amplification with any thermal cycler with enough ramp rate of ≥ 1°C/s (i.e. ProFlex PCR System 3x32-Well and 96-Well, Life Technologies)

Compatibility with CE-IVD downstream sequencing software

Validated with:
- DeepChek software (CE-IVD) HIV module (NGS outputs)
- ViroScore Suite (CE-IVD) HIV module (Sanger sequencing outputs)

Examples of reports

For SANGER sequencing
