Performed: Mon-Sat Reported: 6-9 days |
| Specimen Required: | |
|
Collect: One 6 mL SST or plain red.
Transport: 3 mL serum at 2-8 °C. (Min: 1 mL) Also acceptable: CSF. Pediatric Collection/Transport: 0.25 mL serum at 2-8°C. Remarks: Separate serum from cells ASAP.

| Reference Interval: |
|
Echovirus 6: Less than 1:10 Echovirus 7: Less than 1:10 Echovirus 9: Less than 1:10 Echovirus 11: Less than 1:10 Echovirus 30: Less than 1:10 |
| Interpretive Data: | |
|
Single positive antibody titers of greater than or equal to 1:80 may indicate past or current infection. Seroconversion or an increase in titers between acute and convalescent sera of at least fourfold is considered strong evidence of current or recent infection.
