Has anyone had allergen tests?

[Eesha]

Just thinking whether it's worth me having an allergen test in case there's anything else I need to be aware of given my weight just doesn't move at all.

I would look at hormones or metabolic or inflammatory conditions like perimenopause, pcos, prediabetes, insulin resistance, underactive thyroid, lactose intolerance etc.
Focus on a high protein low carb diet and track your calories on an app like myfitnesspal. Aim to do strength and resistance training to build muscle which burns more fat.

Having an allergy won't cause you not to be able to lose weight. If you have allergy symptoms then they need investigating of course, but finding out if you have allergies to pollen, dust mites, food, animals etc won't help you understand why you can't lose weight.
