Frequently Asked Questions About Milk Somatic Cell Counters

Choosing the right somatic cell counter for your dairy farm or laboratory is an important decision. We've compiled answers to the most common questions we receive about CytoVue milk somatic cell counters to help you make an informed choice.

General Questions

Q1: What is a milk somatic cell counter and why do I need one?

A: A milk somatic cell counter is a diagnostic device that measures the number of somatic cells (primarily white blood cells) in milk samples. Elevated somatic cell counts (SCC) indicate udder inflammation, typically caused by mastitis infection.

You need a somatic cell counter to:

• Detect subclinical mastitis before visible symptoms appear
• Monitor treatment effectiveness
• Make informed culling and dry-cow therapy decisions
• Meet milk quality standards and avoid penalties from processors
• Improve overall herd health and milk production
• Increase farm profitability by reducing mastitis-related losses

Q2: How does the CytoVue somatic cell counter work?

A: CytoVue uses advanced fluorescent staining and optical detection technology. The process is simple:

1. A small milk sample is mixed with a fluorescent reagent that binds to cell DNA
2. The stained sample is analyzed by the device's optical system
3. Fluorescent signals are counted and converted to somatic cell count
4. Results are displayed on screen within 2 minutes

This method is based on the same principle as laboratory flow cytometry but in a portable, user-friendly format.

Q3: Is the CytoVue counter suitable for small farms or only large dairies?

A: CytoVue is suitable for farms of all sizes:

• Small farms (5-20 cows): Affordable investment with quick ROI through early mastitis detection
• Medium farms (20-100 cows): Essential tool for routine herd health monitoring
• Large dairies (100+ cows): Cost-effective alternative to sending samples to laboratories
• Veterinary practices: Portable device for on-farm consulting services
• Milk collection centers: Quality control at point of collection

Technical Specifications

Q4: What is the detection range and accuracy of CytoVue?

A:

• Detection range: 0 to 50,000,000 cells/mL
• Accuracy: ±5% compared to reference flow cytometry methods
• Repeatability: CV (coefficient of variation) < 5%
• Correlation with reference methods: R² > 0.95

This accuracy meets international standards for somatic cell counting and is suitable for both diagnostic and regulatory compliance purposes.

Q5: How long does it take to get results?

A: Approximately 5 minutes per sample from sample preparation to final result. This includes:

• Sample preparation: 3 minutes
• Instrument analysis: 2 minutes
• Result display and recording: Immediate

This is significantly faster than sending samples to a laboratory (24-48 hours) and allows for immediate treatment decisions.

Q6: What types of milk can be tested?

A: CytoVue can accurately test:

• Cow milk (all breeds: Holstein, Jersey, Brown Swiss, etc.)
• Buffalo milk (important for Asian and Mediterranean markets)
• Goat milk
• Sheep milk (with appropriate calibration)

The device works with both individual quarter samples and composite (whole udder) samples, as well as bulk tank milk.

Q7: Can it test frozen or refrigerated milk samples?

A: Yes, but with important considerations:

• Fresh milk (preferred): Best accuracy, test within 2 hours of collection
• Refrigerated milk (4°C): Stable for up to 48 hours; warm bath for 10mins to temperature (40°C) before testing
• Frozen milk: Not recommended as freezing can damage cells and affect accuracy
• Preserved samples: Compatible with standard milk preservatives (e.g., bronopol, azidiol)

Operation & Maintenance

Q8: Is the device difficult to operate? Do I need special training?

A: No special training is required. The CytoVue counter is designed for ease of use:

If you can operate a smartphone, you can operate a CytoVue counter.

Q9: What maintenance is required?

A: Minimal maintenance keeps the device running smoothly:

Daily (if used):

• Wipe exterior with clean, damp cloth
• Ensure sample chamber is clean

Weekly:

• Clean optical components with provided cleaning solution
• Check reagent levels and restock if needed

Monthly:

• Run calibration check with control samples
• Inspect consumables and order replacements as needed

Annually:

• Professional calibration service (optional)
• Battery replacement if needed

Total maintenance time: Less than 15 minutes per week.

Q10: How long does the battery last?

A: The rechargeable lithium battery provides:

• Up to 190*4 tests on a single charge (depending on usage patterns)
• Recharge time: 3-4 hours for full charge
• Battery life: 500+ charge cycles (approximately 3 years of typical use)

The device can also operate while plugged into AC power for continuous laboratory use.

Q11: What consumables are needed and how much do they cost?

A: Required consumables include:

This is significantly lower than laboratory testing fees ($5-15 per sample) and provides immediate results.
