Choosing an isolation gown for a veterinary clinic comes down to matching the barrier level to the task rather than to the largest number on the box. AAMI PB70 defines four levels, and most small-animal and mixed practices need Level 1 for handling and Level 2 for fluid-heavy work such as dentistry and wound lavage. This guide explains what each level tests, which setting it fits, and how to document the choice for a provincial inspection.
What does the AAMI PB70 level actually measure?
AAMI PB70 is the North American standard that grades the barrier performance of isolation gowns and similar protective apparel. Level 1 is the lightest and is measured with a water impact test at 4.5 g, Level 2 at 7.0 g, and Level 3 at 10 g, while Level 4 adds an ASTM F1671 viral penetration test. The number describes how much liquid the fabric resists under a defined impact, so a higher level is not automatically the right gown for every room. Level 4 is the only level defined by viral penetration rather than by water impact alone, and that single fact is why a quiet exam room rarely needs it.
Which gown level does a veterinary exam room need?
A routine exam room handles healthy animals, quick palpation, and minimal fluid, so Level 1 non-woven gowns are usually enough. Level 1 apparel is made for minimal fluid contact and short interactions, and it keeps a busy practice from spending surgical-grade money on general handling. For a veterinary clinic the practical rule is to stock Level 1 for the treatment floor and reserve heavier gowns for the rooms where splashes or sprays are predictable.
Do veterinary surgeries need a higher gown level than routine exams?
Yes, surgery and dentistry are the two areas where fluid contact rises sharply, and Level 2 SMMS gowns are the common fit. A Level 2 gown is tested with a higher water impact than Level 1 and is intended for low-to-moderate fluid exposure, such as lavage, dental scaling with irrigation, and wound flushing. Some referral practices move to Level 3 for open procedures, but the decision should follow the procedure list rather than the size of the clinic. A mixed practice that runs both exams and surgery in the same building should keep both levels within easy reach of the treatment area.
| AAMI PB70 level | Barrier test | Typical veterinary use |
|---|---|---|
| Level 1 | Water impact 4.5 g | Exam rooms, animal handling, minimal fluid |
| Level 2 | Water impact 7.0 g | Dentistry, wound lavage, low-to-moderate fluid |
| Level 3 | Water impact 10 g | Higher-fluid procedures, referral surgery |
| Level 4 | ASTM F1671 viral penetration | Highest-risk fluid and pathogen exposure |
Do isolation wards in a veterinary hospital need a different gown?
An isolation ward is about containment as much as fluid, so clinics often add a Level 2 gown plus a change protocol rather than jumping straight to Level 4. The gown is one layer of a routine that includes dedicated footwear, hand hygiene between rooms, and a clear donning and doffing order. Where the risk is a known pathogen with a body-fluid route, a Level 3 gown and full coverage give more margin. The decision belongs to the same task list that drove the exam-room choice, just with containment added as a second column.
How do you match a gown level to a veterinary setting without overbuying?
Start with a short list of tasks and mark the fluid load next to each one, then assign the lowest level that covers the load with a margin. CliniEco keeps a Level 1 non-woven isolation gown for exams and handling and a Level 2 SMMS gown for dentistry and lavage; both sit in the isolation gowns collection so a practice can standardise on two SKUs instead of five.
Thickness is a useful signpost but not the whole story. A 40 gsm SMMS fabric at Level 2 will usually feel firmer and resist more spray than a thin Level 1 non-woven, and both are single-use. If a practice is torn between two SKUs, buy a case of each, run them for a month in the rooms where they will actually be worn, and let the staff report on comfort and coverage. That small trial costs less than standardising on the wrong level for a year.
How many gowns should a veterinary clinic keep in stock?
Size the order from the busiest week, not the average one. Count the procedures that need a gown, multiply by the days the clinic is open, and add a buffer for isolation cases and reorders. A practice that keeps two sizes in each level rarely runs short, because the small and large cases cover most of the staff. Store the gowns in the room where the task happens, so a technician is not walking down a corridor in a used gown to find a replacement. Place the isolation gown collection next to the reprocessing sink so the workflow stays in one zone.
Does the gown level change the price much?
Gown cost rises with the level, but the gap is smaller than most practices assume, and the hidden cost is the wrong SKU in the wrong room. A Level 1 gown used for a dental procedure fails the fluid check and forces a second gown and a second pair of gloves, which erases any saving. A Level 3 gown used for a healthy exam is simply money spent on barrier the room does not need. Standardising on two levels lets a practice buy deeper case quantities and keep the price predictable from month to month.
Clinics that reprocess instruments in Ontario are also tightening their records. In dental settings the RCDSO expects a biological indicator every day the sterilizer is used, which is daily, not weekly. The weekly rhythm is the CDC / AAMI ST79 baseline in most US states, and it should not be read across as an Ontario expectation. Keeping the gown level and the monitoring record in one binder makes an inspection short.

Frequently Asked Questions
What AAMI PB70 level is a standard veterinary exam gown?
Level 1 is the usual choice for a routine veterinary exam room, because the interaction involves minimal fluid contact and short handling time.
Is Level 2 enough for veterinary dentistry?
Level 2 SMMS gowns are the common fit for dentistry and wound lavage, where splashes and spray are predictable but not sustained.
Does a higher AAMI level always mean a safer gown?
A higher PB70 level means more fluid resistance rather than a better fit for every task, so matching the level to the procedure keeps the practice comfortable and controlled.
Where can a Canadian veterinary clinic buy isolation gowns in case quantities?
CliniEco supplies Level 1 and Level 2 gowns by the case with Canadian warehouse delivery, and the wholesale page lists multi-site and case pricing.
