Reason for Recall

Focus Diagnostics is recalling Simplexa™ Herpes Simplex Virus 1 & 2 Direct and Simplexa™ Group A Strep Direct kits containing the Direct Amplification Discs due to poor lamination between the sample reaction wells. This poor lamination may lead to leakage into adjacent wells causing cross-contamination between samples, which could yield false positive, false negative, or invalid test results. Inaccurate diagnostic test results may lead to improper patient treatment for HSV or GAS and may cause serious adverse health consequences, including death. 

Who May be Affected

  • Health care professionals using these kits to diagnose HSV 1 & 2 or GAS infections
  • All patient groups receiving a HSV 1 & 2 or GAS infection diagnosis using these kits

What to Do

On February 10, 2016, Focus Diagnostics sent a Customer Correction Notice letter to customers letting them know extra discs would be provided free of charge until the issue was resolved. The letter also asked customers to:

  • check their inventories for defective products
  • only run full discs
  • avoid running partially used discs
  • discard discs even after a partial run
  • acknowledge receipt of the letter by returning the enclosed form or by contacting Focus Diagnostics by email at or by fax at 562-240-6526
  • report adverse events or quality problems experienced with use of the product may also to the FDA
