Guidelines for sampling tissue for PCR analysis v. 1.2
It is important to ensure good quality of tissue samples in order to obtain a correct PCR test result,.
Equipment that prevents contamination between samples should be used when sampling.
 
Recommended equipment:
  • Sample tubes containing RNAlater (ordered from Blue Analytics AS).
  • Tweezers and scalpel.
  • Optional sterilization equipment in the form of a gas burner or 10% chlorine solution.
  • Tissue paper for cleaning equipment before disinfection.
  • Packaging for submission (styrofoam box).
  • Cooling element.
 
Sampling procedure:
  • The size of the tissue samples is important and should be approximately 2x2x2 mm (10 mg). The ratio of tissue: RNAlater must not exceed 1:10, this to ensure good fixation of the sample.
  • To avoid contamination from any vaccine residues, pieces of tissue must not be taken from the abdominal cavity.
  • Two samples should be taken from the same individual (an A and a B sample) and placed in the same sample tube.
  • Avoid contamination between individuals either by changing disposable equipment or disinfecting the equipment.
  • The order of placement of sample tubes in the box must be vertical (columns). First tube in position A1 (A1, B1, C1 etc.), so that tube 9 is placed in position A2.
  • Position H12 must always be empty, i.e. a full box must contain a maximum of 95 samples. Position H12 is used for internal control at the laboratory.
  • When submitting more than 95 samples, the boxes must be marked with unique serial numbers.
  • Sampling should be done by personnel with special training.

 

Storage and submission:
  • Tissue samples must be kept refrigerated from collection to dispatch. (Correctly RNAlater-fixed samples are stable up to 1 month at 4°C).
  • The samples must be packed in a styrofoam box together with a cooling element.
  • Samples must be sent as an express overnight package. The tracking number for the shipment is to be sent to: mottak@blueanalytics.no
  • The completed Sample submission form PCR-analysis must always be included in the package.
  • Tracking file with sample overview should be sent to: mottak@blueanalytics.no
