Testyourintolerance

Testyourintolerance sells at-home hair- and blood-sample kits that screen for IgG4 and IgE reactivity to 300-900 food, drink, environmental and metal items. Kits are priced £19–£199, placing the range in the budget-to-mid segment. All orders are placed through the brand’s own UK-based e-commerce site; results are delivered digitally within 3-5 days of the lab receiving the sample. The company’s core promise is “no doctor visit required”: a few strands of hair or a finger-prick blood spot are enough to generate a colour-coded intolerance and allergy report plus 4-week elimination diet guide. The lab uses ELISA plate and bioresonance testing and is ISO-9001 certified, a credential few direct-to-consumer rivals display. Best-sellers are the “Complete Sensitivity 900” hair test and the “Essential Allergy 35” blood kit. Typical buyers are 20-45-year-old health- and fitness-oriented adults who suspect unexplained bloating, fatigue, eczema or weight-loss plateaus and want quick, anonymous answers before paying for private gastroenterology or dermatology consults. The brand speaks to value-driven, self-experimenters who track macros, use wearables and prefer natural, drug-free interventions. Testyourintolerance competes with two sets of players: budget eBay/Amazon hair-test sellers that lack accredited labs, and premium clinic-based allergy services that charge £300-plus for physician interpretation. It differentiates by marrying laboratory credibility with direct-mail convenience and mid-range pricing, offering a 100% money-back guarantee if no sensitivities are detected—an assurance low-cost sellers omit.
