ZLB Laboratory

High quality laboratory tests screen each plasma unit for viruses before plasma is approved for manufacturing. Additionally, samples are tested for presence of antibodies suitable for use in manufacture of immunizations. The ZLB Lab is located in Knoxville, Tennessee and employees over 100 staff, a combination of licensed technical, non-technical and support personnel. This testing facility processes millions of samples each year and operates seven days a week.

Viral marker samples: HBsAg (Hepatitis B Surface Antigen), HCV (Hepatitis C Virus Antibody), HIV 1&2 (Human Immunodeficiency Virus 1& 2 Antibodies), ALT (alananine transferase/liver enzyme)
Hyperimmune/Immunology samples: HAV (Hepatitis A Virus), Tetanus, VZV (chicken pox), Rabies, Measles, etc.
Donor suitability samples: serum protein electrophoresis, syphilis and unexpected blood group antibodies.
Other Laboratory Testing Nucleic Acid Testing (NAT) is conducted additionally to identify certain viruses. This technology is more sensitive than traditional enzyme immuno assays and is conducted for HIV, HBC, HCV, HAV and Parvo B-19.
Plasma Safety
Every plasma unit has a unique donor number. Bar codes are applied to units of plasma and all associated unit samples that identify donor, donation date and each unit specifically.
