The Twin Sample Biopsy Needle harvests two tissue samples in one pass, one for conventional pathology and the second for molecular diagnosis.

If the pathologist finds tumor tissue in the first biopsy, the second sample can be dissected to provide matching tissue for testing in the molecular assay. 

Paired samples with minimum intrusion

Slides from twin samples of fresh ex-vivo prostate.

2 samples in 1 pass

One sample satisfies pathology and ethical requirements for patient treatment, leaving the second available for molecular assays. Since the second mirrors the first, the pathologist’s findings tell you what is in the second sample. Get the Right Sample for precision medicine.

Sample Custody

The fresh sample is sent from the biopsy procedure directly to the extraction lab to provide analyte for everyone. No more tracking a single biopsy, multiple blind biopsies or finding the remaining block inadequate.

High quality tissue

Fresh tissue is best for molecular assays. With a median sample size of 3.5 mg, there is more than enough DNA, RNA and protein to satisfy all assay requirements. Eliminate between-sample variance and have everyone testing the Right Sample

Requires a Team Approach

Precision medicine protocols necessitate a coordinated approach, for example:

  • Oncologist orders biopsy and tests (justfying 16G needle)
  • Interventional radiologist performs twin sample biopsy in one pass
  • Pathology does Rapid On-Site Evaluation (ROSE) of the first sample
  • Molecular pathology lab performs extractions
  • Molecular labs specify requirements for aliquots
  • Pathology findings on first sample slides optimally accompany molecular aliqouts
  • Biobank retains extra material for future use

In this way getting accurate results – without contradictions – can become routine.
