MICHAEL HARDCASTLEWe frequently receive incisional biopsies (e.g. wedge, Tru-cut or punch biopsies) of enlarged lymph nodes. Unfortunately these can be unsatisfactory for multiple reasons and excisional samples (i.e. removal of the entire node) are preferred.The main issues with incisional biopsies relate to sample distortion. Since lymphocytes are fragile and lymph nodes have a delicate supporting […]
GEOFF ORBELLIt is the time of year when we are seeing a lot of foreign body reactions due to migrating grass awns through the lab at the moment.These are usually due to barley grass (Critesion spp.) of which there are six different species in New Zealand, but other grass species can also be culprits.

These faecal samples were recently sent to our laboratory packed inside a plastic bread bag and were leaking everywhere on receipt. They provide a good example of inappropriate/illegal sample packaging.Plastic bags tear easily, are prone to leakage, are awkward to extract samples from, do not meet the legal requirements for biological samples and are not […]

Classically we think of the cresty-necked, overweight horse or pony that can live on the smell of an oily rag. However not every overweight horse has EMS and occasionally some horses with normal body condition may have EMS (so called […]

RACHEL WHITEHEADGrazing ruminants in New Zealand are rarely free of worm infection, though effects on stock health and productivity vary widely. Clinical effects of enteric parasitism include ill thrift, diarrhoea, anaemia, and death in severe cases.The degree of damage is influenced by the numbers and identities of the parasites present, host age, immunity, general health, […]
AREFEH RAVANBAKHSHMastocytemia refers to presence of mast cells in peripheral circulation. Mast cells originate from precursor cells produced in the bone marrow and following migration into peripheral tissue, they undergo further differentiation and maturation. Once in tissue they do not tend to recirculate and thus are not normally found in peripheral blood.1 The morphology of […]
Often we receive forms with faint writing or ticks (or barely legible writing) and it does make it really hard to figure out exactly what you require.When completing submission forms and ticking boxes, please make sure you use a decent, dark pen to write with. This will ensure we can clearly read all information provided, […]
