Specimen Collection Details
| |
Collection
| One 7 ml red top tube or serum separator tube (SST). | |
Optimal Volume
| Blood: 5-7 ml; Serum 1-2 ml | |
Minimum Volume
| Blood: 3 ml; Serum 0.5 ml | |
Handling
| After blood clots, keep specimen refrigerated until transport. If possible remove the serum from the clot as soon as possible. DO NOT FREEZE. Sample must be tested within 7 days of collection. | |
Transport
| Transport refrigerated at 2-8° C within 5 days. | |
Rejection Criteria
| Specimens other than whole blood in a standard Red Top tube or serum are not suitable for testing.  The following are unacceptable for testing: grossly hemolyzed specimens; bacterially contaminated specimens, and heat-inactivated specimens. | |
Comments
| This test is intended for use in the confirmation of immunity to VZV. In addition, seroconversion between acute and convalescent sera is considered strong evidence of current or recent infection. The best evidence for infection is a significant change on two appropriately timed specimens, where both tests are done in the same laboratory. |
