OptiSpot®
Sample Requirements
OptiSpot® card (for Serology testing)
Lancet or needle
Collection Instructions
The Opti-Spot® cards are constructed with 5 individual strips separated by perforations.
The strips can easily be separated along the perforation lines for individual use if needed. On each strip, a 1 cm² circle is printed on the face of the Opti-Spot® membrane as a guide.
It is not necessary that the blood spot be centered within the circle.
Label one Opti-Spot® card with a unique identification number for each sample strip. Ante-mortem blood samples may be obtained by lancing the lateral saphenous, facial or the temporal vein.
Touch the Opti-Spot® membrane to blood drop as it forms on the surface of the skin. If the blood sample is taken by cardiocentesis, quickly dispense one drop of whole blood onto the Opti-Spot® strip. T
he blood spot should be of sufficient size (approximately 1 cm²) to nearly fill the printed circle and be of sufficient volume to saturate the membrane.
The blood spot will appear similar on both sides of the membrane.
Allow the blood spot to dry for a minimum of one hour.
Once dried, fold the protective upper tab over the blood spot and tuck under the lower tab.
Sample Storage
It is important that the Opti-Spot® strip is protected from moisture.
Shipping
Once dry, place Opti-Spot® samples in a water-tight plastic bag containing the provided silica gel desiccant pack, and ship samples in a standard overnight envelope shipped at ambient temperature.
Turnaround Time
3 business days
Additional Information
Refrain from pooling serum samples on OptiSpot® strips, a practice that can yield false negative results by dilution effect.
Serum
Sample Requirements
Serum (for Serology testing)
1.5 mL centrifuge tube
Collection Instructions
MFI2 requires only 0.2 µl of undiluted serum (1.0 µl of 1:5 diluted serum) regardless of the number of tests requested.
To allow for potential secondary and tertiary confirmatory testing, we recommend that a minimum of 20 µl of undiluted (100 µl of 1:5 diluted serum) be submitted for each sample.
You may achieve an approximate 1:5 dilution of serum by adding 1 part of whole blood to 4 parts of ambient temperature saline.
Refrigerate the diluted blood for 6 to 12 hours, centrifuge at low speed for 5–10 minutes, and recover the 1:5 diluted serum for submission.
Undiluted serum is preferred.
Sample Storage
Serum and plasma should be stored in tubes with the lids secured to prevent leakage. The use of Parafilm™ over tube lids is recommended to prevent leakage.
Shipping
Serum samples should be shipped frozen using an overnight service.
One or two ice packs are generally adequate depending on the type of container, the number of samples and the ambient temperature.
Optimal shipping conditions are achieved when the entire package with its lid open is frozen overnight at or below -20˚C.
Close tubes when shipping samples.
The use of dry ice is not required.
Turnaround Time
3 business days
Additional Information
Do not submit whole blood; hemolysis will occur during freezing or shipping and may interfere with serologic test performance.
Refrain from pooling serum samples, a practice that can yield false negative results by dilution effect.
Please include a completed serology submission form specifying the species, serum dilution, and the serology profile or individual test(s) requested.
Describe any potential biohazards associated with the samples.
Please use a separate serology accession form for each species and serologic profile or group of test(s) requested.

Histology sample collection & shipping
Sample Requirements
Organs, tissue (for Histology)
Collection Instructions
Place tissues in formalin for at least 24 hours before shipment. Tissue to formalin ratio should be 1 to 20 for proper fixation.
Whole rodent and tissues such as lung, brain, bone marrow and spinal cord have specialized collection protocols.
Make sure tissues are not tightly packed in jars or cassettes. Smaller tissues can be placed in a cassette or submitted attached to surrounding organs.
Label cassettes with a pencil. Even indelible ink will fade during processing.
Tissues can be shipped in 70% alcohol or formalin. If you plan to perform IHC testing after preparation, please consult with our Client Support Services team for the proper fixation protocol.
Store fixed samples at room temperature. Frozen samples must be stored and shipped on dry ice.
Sample Storage
Shipping
To preserve sample integrity and prevent leakage samples should be triple-bagged with each layer tied, knotted or secured individually.
Screw-topped containers are preferred. Make sure the lid is tightly secured to the jar and place a layer of Parafilm or tape to secure the lid to the jar.
Invert the jar to check for leaks and reseal if needed.
Place jar(s) into one gallon sealable bag with absorbent material such as paper towels and seal the bag.
Place samples in a sealable bag in a second sealable bag and seal or double-line (one bag inside of another) the shipping box with large garbage bags and tie off each bag separately.
Prior to knotting the first garbage bag, place absorbent packing materials around the bagged samples to not only absorb any leaked fluid but to prevent jostling and stabilize samples during shipment.
If sample jars are too large to seal in a one gallon sealable bag, you can also use garbage bags to triple line the shipping container.
Absorbent material should be placed around the samples in the first garbage bag prior to tying a knot in the bag.
Place the Histology Submission Form(s) or online submission packing slip and other supporting documents (if needed) on the outside of the second garbage bag.
Do not tape the inventory form to the outside of the box or place with samples in the same sealable bag.
Turnaround Time
Varies based on services requested.
