Pregnancy tests are locked up in stores primarily because they’re one of the most commonly stolen items in retail pharmacies. The reasons behind the theft are a mix of the product’s relatively high cost for its size, the embarrassment some buyers feel at the checkout counter, and the ease of slipping a small box into a pocket. For retailers, locking them behind glass or attaching security tags is a straightforward loss-prevention decision, even though it creates an awkward experience for shoppers.
Small, Expensive, and Easy to Steal
Pregnancy tests typically cost between $1 and $15, with popular digital brands sitting at the higher end of that range. That might not sound like much, but the boxes are small and lightweight, making them easy targets for shoplifting. Retailers lose billions of dollars each year to what the industry calls “shrink,” and they focus security efforts on items with a high theft-to-size ratio. Pregnancy tests check that box alongside razor blades, expensive batteries, and certain electronics.
The profit margin on these products also matters. A single stolen pregnancy test might only cost the store $8 at retail, but when dozens disappear from a location each month, the losses add up quickly. Stores make decisions about which items to lock up based on internal shrinkage data from individual locations, which is why you might find pregnancy tests behind glass at one store but sitting freely on shelves at another across town.
Embarrassment Drives Theft Too
Price isn’t the only factor. Pregnancy tests belong to a category of products that people sometimes steal not because they can’t afford them, but because they’re embarrassed to bring them to the register. Teenagers and young adults are especially likely to pocket a test rather than face a cashier. In Germany, for example, stores apply security locks to both pregnancy tests and condoms for this exact reason: they’re products people would rather not be seen buying.
This pattern creates a feedback loop. Stores notice high theft rates on pregnancy tests, so they lock them up. The locked case draws even more attention to anyone asking a store employee to open it, which increases the very embarrassment that drove some of the theft in the first place.
How Stores Decide What Gets Locked
Retailers don’t have a universal list of products that go behind glass. Each chain, and often each individual store, makes locking decisions based on its own loss data. Walmart has described its locked-case policy as targeting “electronics, automotive, cosmetics and other personal care products” with high shrinkage rates. Walgreens and CVS follow similar logic, reviewing theft numbers at the store level and adjusting which aisles get security treatment.
This store-by-store approach explains the inconsistency shoppers notice. A pharmacy in a busy urban area with high foot traffic and frequent theft might lock up pregnancy tests, Plan B, and baby formula, while a suburban location of the same chain keeps everything on open shelves. The decision is driven by local loss numbers, not a corporate mandate about pregnancy tests specifically.
Locked Cases Aren’t the Only Security Method
Glass cabinets are the most visible form of security, but many stores use less obvious methods. RFID tags, small stickers or plastic strips hidden inside or on the packaging, are increasingly common. These tags trigger the alarm towers at store exits if they haven’t been deactivated at the register. You’ve probably encountered this if a self-checkout machine flagged your pregnancy test and required a store employee to clear the transaction.
The RFID stickers can be tiny, sometimes disguised as a barcode label or tucked between layers of cardboard packaging. They’re cheap for stores to deploy and don’t require a locked cabinet or employee assistance, which makes the shopping experience less intrusive. Some retailers are moving toward this model specifically because locked cases frustrate customers and can reduce sales. If you have to wait five minutes for someone with a key, you might just leave without buying anything.
The Access Problem This Creates
Locking up pregnancy tests has a real downside beyond inconvenience. For someone who needs to confirm a pregnancy quickly, having to flag down a store employee, wait for a key, and make the purchase under what feels like supervision can be a genuine barrier. This is especially true for teenagers, people in abusive relationships who need privacy, or anyone who already feels anxious about a potential pregnancy.
The barrier also tends to fall unevenly across neighborhoods. Stores in areas with higher reported theft rates are more likely to lock products behind glass, and those areas often overlap with lower-income communities. The result is that people with fewer resources and less access to alternatives face more friction when trying to buy a basic health product.
Where to Get a Test Without the Hassle
If locked cases feel like too much of a barrier, you have options. Dollar stores carry pregnancy tests that work just as well as premium brands for a fraction of the cost, and they’re rarely locked up. Online retailers ship tests discreetly, often in multipacks for less than the price of a single box at a pharmacy. Community health clinics, Planned Parenthood locations, and county public health departments offer free or low-cost pregnancy testing, often with same-day results and no questions asked. Many local family health hotlines can connect you with a nearby provider that offers confidential testing at no charge.
The basic technology inside a pregnancy test is the same whether you pay $1 or $15. Expensive digital tests that display “Pregnant” or “Not Pregnant” on a screen use the same detection method as a simple strip test from a dollar store. Both detect the same hormone in urine, and both are over 99% accurate when used on or after the day of a missed period. The locked-up brand-name test at your pharmacy isn’t more reliable than the unlocked alternative somewhere else.
