The processes involved in handling, processing, storage, and communication of informatics can be tailor-made to suit your needs too. Below is a breakdown of how informatics can be stored, processed and integrated into your systems or networks.
It all starts with samples that have been either stored in our biorepository or sent to us directly for analysis. Regardless of whether they have been stored with us for days or decades, we are able to retrieve and analyse samples immediately as our labs and biorepository are both on premises, reducing overall turnaround times.
What informatics do you provide?
Using our cutting-edge platforms from Illumina, PacBio, Fluidigm, ClearDX and more, we can customise arrays or sequencing investigations to fit your requirements, whether they involve “off the shelf kits” or bespoke panels. Furthermore, we are able to accommodate a wide range of samples for testing from several different sources including:
- Other animal species

Sanger data analysis and reporting
How is my raw data processed?
The first step undertaken is to deliver the raw data to clients, this ensures transparency as well as giving you the ability to forecast or predict what level of processing is required for the data that has been collected.
The next step involves secondary analysis, for example, data generated from genotyping/gene expression by sequencing and methylation sequencing will require reads to be aligned to respective reference genomes. Similarly, VCF files will be generated from any genotyping by arrays.
Reports from tertiary analysis are listed as follows:
- Genotyping by array – PLINK Analysis and Imputations
- Genotyping by sequencing – gVCF files, Structural Variant reports, Copy number variants reports
- Gene expression by arrays – Differential Gene/Transcript expression profiling and statistical analysis
- Gene expression by sequencing – Gene/Transcript level quantification, Differential expression analysis
- Methylation by array – Methylation report
- Methylation by sequencing – Methylation report, differentially methylated sites analysis
The fourth and final form of analysis involves custom post processing which is requested on a case-by-case basis. Typically, these include:
- Genotyping – QC metrices are reported and custom panel analysis can be included upon request
- Gene Expression – Pathway analysis/Gene Enrichment analysis
- Methylation – Available upon request
How is my raw data/reports stored and shared?
There are two forms of informatics storage we offer at Sampled. Raw data/reports can be stored physically on our highly resilient Dell EMC Isilon storage system which can hold up to 1.2 Petabytes. Additionally, we offer cloud-based storage system – AWS S3, here data can be encrypted upon request. In either format, data can be stored and retrieved at any time by clients and removed from our databases upon request too.
Generating and storing your informatics is important, but we also believe in the importance of seamless client integration, one example of this is how we integrate with clinical EHR systems (for hospitals, clinics etc.) to receive test orders into a HIPAA compliant and secure server using the HL7 protocol. Moreover, test results can also be sent back to HER systems via end-to-end encrypted HL7 messaging through private VNP tunnels. If you have specific platform or system integration requests, we are always willing to accommodate these requirements where possible.
Alongside HL7 based encrypted messaging, Sampled supports a variety of transmission protocols including SFTP based transmission (which includes SFTP setup for clients) as well as API based result transmission (including custom API set up for clients)
Electronic Health Record data transmission via HL7
Sampled supports bidirectional controlled PHI data transmission to and from Sampled using HL7 standards on a secure end to end encrypted network. We provide integration support to our clients for connecting and sharing test results using HL7 protocol.
Data warehousing and integration of multi-omics data
We provide data warehousing services and help integrate client data coming from multiple technologies to a single platform, this could include Genomic, transcriptomic, proteomic, lipidomics data etc. This data warehousing service enables users to interrogate their population in a variety of ways to identify patient cohorts, share data, and run additional analysis on banked specimens at Sampled.
