Check Mark Laboratory is a division of Dairy One and one of the leading wet chemistry laboratories in the northeast. All laboratory staff are certified by the New York State Department of Agriculture and Markets. The laboratory conducts chemistry testing for fat, protein, total solids, casein, and lactose.  Check Mark can analyze any liquid dairy product for these components.  These may include and are not limited to: heavy cream, whey, retentate, yogurt, milk replacement products, reconstituted powders, or non-bovine milk.

When sending samples, please make sure to include a completed copy of the Sample Submission Form.

The Check Mark laboratory also manufactures raw milk calibration standards each week to be used in other labs across the region. We can develop customized calibration standards specifically for your IR analyzer to monitor your specific dairy product.

The component calibration samples (used to calibrate for fat, protein, etc) are shipped on Tuesday via UPS and the results are made available by Thursday afternoon.  The somatic cell control samples are shipped on Wednesday afternoon.  Shipping and handling is included in the prices with Next Day or Second Day at an additional cost.  Customer pays the fee to return the shipping container.
