Application

Upper respiratory tract infections (URTIs): common cold, influenza, rhinitis, pharyngitis, tonsillitis, laryngitis, etc.
Lower respiratory tract infections (LRTIs): tracheitis, bronchitis, bronchiectasis, bronchiolitis, pneumonia, lung abscess, etc
Mycobacterial infections: pulmonary tuberculosis and nontuberculous mycobacteria (NTM) lung disease, etc.
Chronic respiratory infections: chronic obstructive pulmonary disease (COPD), asthma, etc.

Applicable for the detection of respiratory specimens, including oropharyngeal/nasopharyngeal swabs, sputum, bronchoalveolar lavage fluid/bronchial washing fluid, pleural fluid/ascites, and lung biopsy tissue.

Workflow

Feature

Sample-in, result-out; TAT reduced to 12 hr.
> 99% common clinical pathogens + ~200 AMR markers.
Specific detection of low-load pathogens with stable, reliable results.
End-to-end QC to reduce false positives.
AMR markers identification with source-microbes attribution.
Fine-resolution genotyping and variant analysis for key RNA viruses.

Performance

Stable Detection of Multiple Pathogens in Reference Standard

Table 1. Limit of detection (LoD) of the μCaler RIA Solution for multiple pathogens in reference standard.

A total of 0.4 mL of reference standard at diﬀerent concentration gradients was used for extraction of mixed RNA & DNA. Pre-libraries were prepared using the NadPrep EZ RNA & DNA Library Co-Preparation Module coupled with the NadPrep Universal Stubby Adapter (UDI) Module. Hybrid capture was performed using the μCaler HyperMix Hybrid Capture Kit (for Illumina®) and the μCaler RIA Panel v1.0. Sequencing was performed on MiSeq with PE150, with raw data of 3 M read pairs per sample.

Note: RPM stands for reads per million mapped reads.

Signiﬁcantly Improved Detection Rate for Clinically Important Pathogens

Figure 1. Heatmap comparison of detection concordance among the μCaler RIA Solution, mNGS, and culture for key clinical pathogens.

Note: Light blue and light gray blocks indicate positive and negative results, respectively; white block indicates the method is not applicable, and no valid result could be obtained. Samples were collected from 78 clinical patients, including multiple specimen types such as sputum and BALF. Clinically important pathogens included in the analysis were: MTBC (M. tuberculosis complex), NTM (nontuberculous mycobacteria), Nocardia spp., P. jirovecii, A. fumigatus, and C. neoformans.
