Additional Specimen Collection Information

Collect blood in a red-top tube. Separate serum from contact with the cells within 2 hours of collection. Maintain sterility of serum and transfer 2 ml of serum to a sterile plastic screw-capped vial. Label the specimen appropriately with two identifiers, patient name and another identifier, (patient ID number, DOB, etc.) include date and time of collection. Unlabeled specimens will be rejected.

A convalescent blood sample collected 14-21 days after acute specimen is required for complement fixation testing and is recommended for most serologic studies.

  1. Wrap the specimen in absorbent material and place in a biohazard bag.
  2. Only one specimen per biohazard bag.
  3. Include the completed request form in the side pocket of the biohazard bag.
  4. Place the specimens in a Styrofoam container with sufficient freezer packs on top to maintain specimens at 4°C until shipment. DO NOT USE WET ICE.
  5. Ship multiple specimens in packaging compliant with USPS or IATA regulation.


Typically completed within 30 days after the specimen is received at the reference laboratory, however this may be variable due to circumstances out of control of the State Hygienic Laboratory.
