Scrapie Susceptibility Testing

Gene Check offers both codon 171 and codon 136 Scrapie Susceptibility Tests for all breeds of sheep. Tests for codon 154 and codon 171 "H" or "K" allele are also available. All tests can be run from a single blood or tissue sample. Results are reported rapidly and confidentially.

Scrapie Susceptibility Test Prices:

Test Price
Scrapie Codon 171, 136, or 154 (1 test) $11
Scrapie Codon 171 & 136 (2 tests) $20
  • Additional testing on archived DNA is $9 for Scrapie, $11 for Spider (per animal, per test)
  • Rush testing is available for a $10 fee (per animal, per test)

* Gene Check does not recommend testing at codon 136 except for QR and some QQ sheep. We do offer "sequential" testing. This is where we will test at codon 171 and then can test at codon 136 based on the 171 genotype. If you would like this done, please denote it on your submission form. Call for details.

Results are reported rapidly and confidentially and are typically available 3-5 business days from receipt of samples. Sequential testing and large lots, particularly during the Spring rush, may require somewhat longer turnaround times. Rush service (results on the second business day after receipt of samples) is available. Contact Gene Check for details.


Gene Check can provide individual certificates for both scrapie susceptibility and spider gene test results. Contact Gene Check for details.
