Complete Blood Counts
Order basic CBCs or CBCs with reticulocytes for routine, sick-patient, and follow-up workups.
Hematology and Coagulation
Submit CBCs, reticulocyte counts, platelet testing, coagulation panels, PT, aPTT, fibrinogen, and related hemostasis tests through B&L.
Hematology and Coagulation Capabilities
Pathologist CBC Review
Request pathologist review when CBC findings or blood cell morphology need additional evaluation.
Platelet Evaluation
Submit manual platelet counts and listed platelet antibody testing when clinically indicated.
Coagulation Screening
Order coagulation panels, PT, and aPTT for initial evaluation of clotting function.
Specialized Coagulation Tests
Review fibrinogen, thrombin time, D-dimer, antithrombin, Protein C, and related assays.
von Willebrand Factor
Submit von Willebrand factor testing as part of a targeted bleeding-disorder workup.
When Practices Use Hematology or Coagulation Testing
These tests support routine blood cell assessment, anemia and platelet workups, and evaluation of suspected bleeding or coagulation disorders.
- 1
A routine or sick-patient workup requires a CBC.
- 2
Anemia assessment needs a CBC with reticulocytes.
- 3
A low or questionable platelet count needs manual review.
- 4
Bleeding, bruising, or prolonged clotting raises a hemostasis concern.
- 5
A procedure or clinical history calls for coagulation screening.
- 6
Abnormal blood cell findings need pathologist review.
Prevent Clotted or Invalid Blood Samples
Hematology and coagulation results depend on the correct tube, complete fill, prompt mixing, and test-specific processing.
Check EDTA samples for clots
Gently invert EDTA tubes immediately after collection. Even small clots can alter cell and platelet counts and may require recollection.
Fill citrate tubes completely
Coagulation testing depends on the correct blood-to-citrate ratio. An underfilled blue-top tube can produce unreliable clotting times.
Use a clean collection
Atraumatic venipuncture helps reduce clotting, hemolysis, and tissue-factor contamination that can affect hematology or coagulation results.
Process coagulation samples promptly
Some assays require separated citrate plasma and specific storage conditions. Follow the B&L test menu for processing and shipment.
Hematology and Coagulation Tests
Review B&L testing for CBCs, reticulocytes, platelets, PT, aPTT, fibrinogen, thrombin time, D-dimer, antithrombin, Protein C, and von Willebrand factor.
Use the B&L test menu to confirm tube type, fill volume, processing, storage, test code, and turnaround details before collection.
Search CBC, platelet, PT, aPTT, or coagulation tests| Test | Code | Turnaround |

Veterinary Hematology and Coagulation FAQs
What hematology tests can practices submit to B&L?
B&L lists basic CBCs, CBCs with reticulocytes, pathologist CBC review, manual platelet counts, platelet antibody testing, and follow-up whole-blood submissions.
What coagulation tests does B&L offer?
The test menu includes coagulation panels, PT, aPTT, fibrinogen, thrombin time, D-dimer, antithrombin III, Protein C activity, and von Willebrand factor testing.
Why must a citrate tube be filled correctly?
Coagulation assays require the proper ratio of blood to sodium citrate. Underfilling changes that ratio and can affect clotting-time results.
What should a practice do if an EDTA sample is clotted?
Contact B&L before shipping when possible. A clotted EDTA sample may not provide a valid CBC or platelet count and may need to be recollected.
