Grifols, the Spanish biotechnology company with a major Triangle presence, is shutting down a test lab in Raleigh that employs 51 people.
The company announced the closing of the facility at 1200 New Hope Road in a letter filed this week with the N.C. Department of Commerce.
Grifols spokeswoman Becky Levine said the closure was announced to employees in April and that the workers were offered transfers to the company's new testing lab in San Marcos, Tex.
Grifols acquired local company Talecris for $3.4 billion in 2011.
Levine said the plan to shift jobs from Raleigh to San Marcos was set in motion several years ago before Grifols acquired Talecris.
Grifols has corporate offices in Research Triangle Park and operates a massive manufacturing facility in Johnston County. It also operates Talecris Plasma Resources, a plasma collection center in Raleigh, and Raleigh Test Lab, a plasma testing facility.
The company employs 2,350 people in the Triangle.
