Sheep Blood Test Reference Ranges — Every Value Sourced

Evidence-based veterinary medicine (EBVM) only. Every value on this page carries a named source.
All 67 values on this page are traced to a named source. A further 4 entries state openly that no interval has been established for that species — those are not values and cite nothing. Most entries are reference intervals; some are thresholds, cut-offs or method-dependent values, and are labelled as such. Every sourced entry is traced to a named laboratory reference document, an established veterinary clinical pathology reference, or peer-reviewed literature — hover it to see where it came from. We never fill a gap by analogy with a related species.

Reference intervals for the sheep — biochemistry, haematology, urinalysis and specialised tests, in one place, with the provenance of every value stated.

Take the data with you. Every row carries the value and the source it came from, so each number can be checked at its origin without coming back here. Free to reuse with attribution.

Read this before you use the table. Reference intervals are analyser- and method-dependent. The interval printed on your own laboratory report always takes precedence over any published table, including this one. These figures are for orientation and teaching. They are not a diagnosis and do not replace examination by a veterinarian.
What kind of proof stands behind each number

Hover any value to see its source and how to check it. The symbol tells you what kind of evidence it is.
