Southend-on-Sea.
Coming to you.
The nearest clinics today, and a way to be told the day we arrive.
The nearest trusted clinic to the centre of Southend-on-Sea is Kalsons Chemist in Westcliff-on-Sea, under a mile away — listed below with two others. Elixir Health plans to run booked testing days in Southend-on-Sea — none is booked yet, and no date is shown that does not exist. If you leave your postcode area, you will be told when one is.
Two things you can do today: be told the day a venue is booked, and open the account your result will live in — so the first visit is the test, not the paperwork.
Find the one nearest you.
The three nearest are below — the closest is 0.9 mi from the centre of Southend-on-Sea. But that is the centre: if you are on the far side of Southend-on-Sea, or out toward the county border, a different clinic may be closer to you. Put your postcode in and we will point you at that one instead.

Where a day would run.
The seafront, the pier and the town centre are a mile or two from the clinic in Westcliff, which runs the full menu today. Elixir Days here are for the venues the clinic cannot reach — a club, a workplace, a residents' room — and for anyone who wants the result explained rather than handed over.

Ten minutes, start to finish.
A quiet room, a table, two chairs. Not a clinical space — a committee room or a members’ room, borrowed for the morning. We bring everything else.
Before
You book from your account. We send one page first: what is measured, what it is not, and that the result is yours.
In the room
About ten minutes. A finger prick, or a small sample taken and spun on site, and the analyser runs it while you sit there.
The result
Printed and talked through on the spot, against the reference range printed for that test. Fifteen minutes, not a week and a PDF.
After
You keep the paper. A GMC-registered clinician reads the panel, and anything that belongs with your own GP is said to you plainly.
What an Elixir Day is — and isn’t.
It is
- A point-of-care measurement, run and explained in the room while you wait.
- The same analyser as every clinic listed on this page, so a number means the same thing wherever you had it done.
- A printed result that belongs to you, read by a GMC-registered clinician.
It isn’t
- Not a diagnosis — a single measurement on a single day cannot be one.
- A laboratory. This is measured at the venue, never sent away; where a lab is the right answer, we say so.
- A clinic or a pharmacy. Elixir is neither, and nothing measured on the day decides anything we send you.
What the analyser measures
Every Elixir Day and every clinic listed here runs the same point-of-care analyser. Each marker, what it measures and how the sample is taken is set out in plain English on one page — what it measures, never what it means for you, which is the clinician's job.

Type your full postcode if it is easier — we only keep the first part (the CM1 in CM1 1GU), because that is all we need to know which days are near you. We keep your name, email and that postcode area. No result, ever, decides whether you hear from us. How that works.
