How to prepare samples for your ProCyte Dx analyzer

Blood collection and sample preparation steps

Procyte Dx blood collection step 1

1. Use an EDTA tube that can be secured in the adapter (13 mm x 75 mm, 1.3 mL, 650 μL). 

Procyte Dx blood collection step 2

2. Use a syringe or vacuum collection system.

Procyte Dx blood collection step 3

3. Draw the sample and transfer, if necessary.

Procyte Dx blood collection step 4

4. Invert the tube to mix​.

Complement your in-house hematology with a high-quality blood film

  1. Use fresh, well-mixed anticoagulated blood to avoid sample deterioration.
  2. Maintain an approximate 30° angle between the spreader and sample slide throughout.
  3. Spread the sample in one smooth, steady motion.
  • Include a blood film when results do not align with clinical expectations.
  • Make sure the film has a symmetrical body, a monolayer, and a feathered edge.
  • Avoid sample deterioration by limiting storage to 4 or fewer hours.
  • Quickly dry slides (air dry or use a fan on the cool setting).

How to run samples on your ProCyte Dx analyzer

  1. Identify the patient and initiate the sample on the IDEXX VetLab Station.
  2. Place the sample in the ProCyte Dx analyzer.
  3. Press the Start button on the ProCyte Dx analyzer and walk away.

Understanding your ProCyte Dx analyzer complete blood count (CBC) results

Dot plots

Dot plots can be used to identify abnormalities within patient samples. Each dot represents an individual cell in this critical component of a complete blood count. Viewed together, they provide a snapshot of cellular morphology.

Maintaining your ProCyte Dx analyzer

Run the rinse procedure once a month



  1. Prepare the 5% bleach solution up to 1 week before running.
  2. Set aside 25 minutes to complete the procedure.
  3. Follow the detailed instructions in your operator’s guide.

Note: This procedure removes contaminants and checks analyzer performance.

Run a quality control once a month

Run a ProCyte Dx quality control once a month


  1. Use a vial of e-CHECK (XS) maintained at room temperature for at least 15 minutes.
  2. Set the QC adapter in the sample drawer and insert the e-CHECK (XS) vial.
  3. Follow the detailed instructions in your operator’s guide.

Note: This QC run ensures the reliability of the analyzer and reagent system.

Change the reagent kit when low, empty, or expired



  1. Fold open the top cover; do not alter the order of reagents.
  2. Avoid damage to the Quick-Connect Top when removing from and placing in bottles.
  3. Follow the detailed instructions in your operator’s guide.

Tip: To maximize reagent use, on the IDEXX VetLab Station, switch off the “Reagent Low” alert.

Clean the fan filter once a month

Technician cleaning the ProCyte Dx fan filter once a month
  1. Turn off the analyzer and open the right-side cover.
  2. Remove and vacuum the fan filter.
  3. Replace the fan filter and close the cover.

Tip: Schedule to coincide with one of your weekly reboots.

Frequently asked questions for the ProCyte Dx analyzer

A variety of maintenance and diagnostic procedures are required to ensure optimal performance of the ProCyte Dx analyzer.

  • Once every 24 hours: Place the analyzer in Standby mode. When you exit Standby mode, two procedures (an Auto Rinse and a background check) are automatically initiated. These take approximately 8 minutes to complete.
  • Every week: Reboot the analyzer and the information processing unit (IPU). 
  • Every month: Clean the air filter, perform the rinse procedure, and run the e-CHECK (XS) L2 quality control. 
  • As needed: Change the reagent kit and stain pack.

Test codes, names, and contents

The IDEXX CBC is the appropriate and most cost-effective option for routine preanesthetic or preventive care screenings on clinically healthy animals. Available for canine, feline, and equine patients, this option provides an automated CBC, including hemogram, five-part differential, platelets, platelet indices, as well as (for canine and feline patients) reticulocyte count and reticulocyte hemoglobin. 

The IDEXX CBC-Select is the option recommended for sick patients as well as for geriatric patients. It includes the same components as the IDEXX CBC, as well as a blood film evaluation by a technician to evaluate for abnormal red and white blood cell morphology, blood parasites, unclassified cells, and immature cell lines. A clinical pathologist review is automatically included when results are markedly abnormal or when unclassified cells are seen based on specific established criteria. 

Blood film evaluation performed by a technologist for RBC and WBC morphology and parasite screen. Pathologist review automatically performed when results are abnormal based on specific established guidelines or if unclassified cells are seen.

Note: Add on to an IDEXX CBC previously performed at IDEXX Reference Laboratories or request following a CBC performed on an in-house IDEXX hematology analyzer (ProCyte Dx or LaserCyte Dx). Must be ordered within 72 hours of specimen collection (within 36 hours preferred for evaluation of cell morphology)

Add on to an IDEXX CBC, avian/reptile CBC, or IDEXX CBC-Select performed at IDEXX Reference Laboratories, or request following a CBC performed on an in-house IDEXX hematology analyzer (ProCyte Dx or LaserCyte Dx). For IDEXX CBC-Select requests, a pathologist review is included and will be automatically performed at no additional charge if specific established criteria are met (see protocol information in the Online Test Directory at

Test code PCOMM is not required for the automatic reflexed pathologist review on IDEXX CBC-Select requests.

Specimen requirements
  • 1 mL LTT
Turnaround time
  • Daily
  • Allow 1–2 working days for pathologist review of CBC if indicated.
Order a profile with your desired CBC options
  • Select the version of the test code ending in 9999.
  • For the IDEXX CBC-Select version, use the same test code minus the 9999.
