Glove selection for healthcare: a decision guide
Most guidance lists glove types. The decision actually runs the other way: sterility, exposure, wear duration, sensitivity – then the product.
Most glove selection guidance lists glove types. That is the wrong order. The decision is driven by the task, and the task answers four questions in sequence: does this need to be sterile, what is the hand being protected from, how long will the glove be worn, and does the wearer have a known sensitivity. The product follows.
Question 1: sterile or non-sterile
Sterile is required wherever the glove will contact a normally sterile body site or sterile equipment: surgery, invasive procedures, central line insertion, urinary catheterisation, wound care on open wounds.
Sterile surgical gloves are hand-specific, individually wrapped in pairs, gamma sterilised, and controlled to a tighter barrier standard – AQL 0.65 for freedom from holes under EN 455-1:2020+A2:2024, against 1.5 for examination gloves. They are also sized numerically, 5.5 to 9.0, rather than XS to XL, because fit tolerance matters more.
Non-sterile examination gloves cover everything else: routine patient contact, injections, phlebotomy, handling specimens, cleaning, food handling.
The distinction is not about cleanliness in general. A non-sterile glove still has a controlled bioburden and must meet the biological evaluation requirements of EN 455-3:2023. It is about whether the site being touched is sterile.
Question 2: what is the hand being protected from
Cytostatic handling deserves emphasis because it is the exposure most often served by the wrong glove. EN 455 compliance says nothing about chemotherapy permeation. The relevant method is ASTM D6978, and results are per drug: most substances show no breakthrough at 240 minutes on a suitable glove, but carmustine and thiotepa break through in tens of minutes even on a sterile surgical glove. If your unit handles cytostatics, require the D6978 table by drug and set change intervals from it rather than from a shift pattern.
Question 3: how long will the glove be worn
For brief, frequent tasks, donning and doffing speed dominates. For sustained wear – a full theatre list, a laboratory shift, a vaccination clinic – the properties that matter are different:
Question 4: sensitivities
Type I – natural rubber latex protein. Immediate hypersensitivity, potentially anaphylactic. A sensitised individual can react to airborne protein without contact. Where a latex-free policy exists, it applies to the whole environment, not to the individual.
Type IV – vulcanisation accelerators. Delayed contact dermatitis, and the more common presentation among staff. It affects nitrile and latex alike, because both are vulcanised with the same accelerator families.
Switching a sensitised member of staff from latex to nitrile does not address Type IV. The answer is an accelerator-free formulation – and the important distinction is that a glove marketed as accelerator-free on the basis of an extraction test showing non-detectable residue is not the same as a glove that never used accelerators. Require a declaration that no accelerators were used in compounding.
For latex-free surgical work, polyisoprene is the standard route: a synthetic whose molecular structure corresponds closely to natural rubber, giving comparable tactility without the protein.
Double gloving
For procedures with elevated perforation or exposure risk – orthopaedics, prolonged surgery, known bloodborne virus – double gloving is the evidence-based practice. See best practices for preventing SSIs.
The system matters more than the doubling. A coloured under-glove beneath a transparent outer glove makes a perforation visible: fluid entering between the layers forms an obvious stain. Matched systems exist for exactly this – our Sempermed® Supreme Duo is supplied as a pack containing both gloves, in latex, and Syntegra Green provides the latex-free equivalent under a Syntegra outer glove.
Wall thickness on the inner glove is reduced so that the doubled assembly retains usable tactility. Two standard gloves stacked is not the same product.
What a specification should state
Six lines cover most clinical requirements:
1. Sterile or non-sterile, and the AQL: 0.65 surgical, 1.5 examination. 2. Standard and edition: EN 455-1:2020+A2:2024, EN 455-2:2024, EN 455-3:2023. 3. Material, and whether accelerator-free by formulation is required. 4. Chemical protection where relevant: EN ISO 374 with the chemicals named, or ASTM D6978 with the drugs named. 5. Powder-free, with the residue figure stated rather than the word. 6. Size range, and cuff length where forearm coverage is needed.
Our range covers examination gloves in nitrile, biodegradable nitrile, long-cuff nitrile and latex, and the Sempermed® surgical range in latex and polyisoprene, with the documentation above supplied per product.
Frequently asked questions
Are vinyl gloves acceptable in a clinical setting? For short, low-risk, non-invasive tasks with frequent changes, yes. Vinyl has the lowest puncture resistance of the three materials and a tendency to separate at the fingertips under stress, so it is not a substitute for nitrile where blood or body fluids are involved.
Does a thicker glove mean better protection? Not reliably. Thickness correlates with permeation resistance but not with puncture resistance, and a thicker film costs tactility, which can increase the risk of the procedure itself. EN 455-2:2024 states directly that absolute force at break does not correlate with in-use performance.
Can we use the same glove for clinical work and food handling? Only if it carries both the medical device declaration and a food-contact declaration. Many nitrile gloves do; it is a certification, not a property of the material, so check the documentation rather than the box symbol.
How often should gloves be changed? Between patients and between tasks, always. Within a task, on a time basis where chemical or cytostatic exposure is involved, using the breakthrough data. Permeation is invisible, so appearance is not a guide.
Do gloves replace hand hygiene? No. Gloves fail, and hands are contaminated during removal. Hand hygiene before donning and after doffing is not optional.
