False Ragweed

False ragweed (Parthenium hysterophorus), also known as parthenium weed, is an invasive plant species native to the Americas but now found across many parts of the world. It belongs to the Asteraceae family and is a notable allergen due to its highly potent airborne pollen. The plant typically flowers in late summer and autumn, releasing pollen that can trigger allergic rhinitis, asthma, and contact dermatitis in sensitive individuals. Inhalant allergy tests often include false ragweed due to its increasing prevalence and allergenic strength.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.
