KCNJ3
KCNJ3 (Potassium Voltage-Gated Channel Subfamily J Member 3): KCNJ3, also known as GIRK1 (G protein-activated inwardly rectifying potassium channel 1), is a gene that encodes a protein involved in regulating neuronal excitability and heart rate. By controlling potassium ion flow, KCNJ3 helps stabilise the resting membrane potential and modulate action potentials in neurones and cardiac muscle cells. Dysregulation of KCNJ3 may contribute to neurological disorders, such as epilepsy and mood disorders, as well as cardiovascular diseases.

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.
