Genetic Testing at Gluck no longer offers regular full blood typing services. Red cell typing will only be performed during April and November. All red cell typing samples should be scheduled to arrive during either of those months, including those for blood donor horses.

Testing for biochemical markers (red top tubes) will also only be performed in April and November.

We will continue to offer serum screening for NI testing on an as-needed basis. Red cell typing of mares should be scheduled during April or November.

Please contact Dr. Kathryn Graves at with any questions regarding blood typing.
