hello there, welcome to the clinic, so today we're going to do a patch allergy test
so I'll just have to take a few notes, ask a few questions before we can begin
now is this your first allergy test?
and do you have any known allergies?
this is where the body might react to something that's normally harmless
that's fine now let me go through some common allergens just to be safe we have: pollen,
house dust mites, food allergies, animal fur or dander, certain medicines or insect bites
no allergies? good, now have you ever been diagnosed with any skin conditions?
are you taking any medication?
and do you have any questions before we begin?
that's great okay I'm going to start by washing the arm,
this area, so the forearm. I'll give it a little dry and then we'll get started
all right let's give the arm a little clean
that's fine
and we're just going to dry the forearm there, just priming the area
okay so we need to apply strip to the forearm, so we know what allergens we're using
okay
just there, keep nice and steady as we do the test. now I'm going to apply some little droplets
which are the allergens to the forearm and then afterwards I'll give this skin just
a little scratch and then we'll give things a period of time
to see if there are any reactions. okay so let's get started with the first sample
okay now this sample it's histamine. we should be looking for
a reaction to the histamine later on. everybody should respond to that one
okay next we're going to apply glycerol saline, and this is just the solution
that everything is dissolved in. some people are allergic to that
there we go
okay and sample number three
is mold
next up
we have yeast
I just want the smallest sample there
next up is tree pollen
lovely
four more to go
there we have dust mites
excellent how are you feeling there?
okay next up is feathers. let's start here
okay and two more common allergies coming up
we have cat
a lot of people are allergic to cat fur, cat dander is that there
and finally, if we've done cats we must do dog
so here we go with the final sample
that is dog
right, that's all the allergens in place
on the forearm, I'm just going to give you just a moment while I prepare the next stage
excellent so now all the samples are in place
I'm going to use a fresh one of these just to gently scratch the skin. we're
not going to draw any blood just a gentle scratch for the allergen to penetrate
the top surface of the skin, the outermost surface just to see if there are any reactions
okay it's not going to hurt, it may just feel a little uncomfortable
excellent work
and
for this
one
and how are you feeling at the moment?
okay
and for the final two
and finally the last sample there
that's very good so I'm going to give you
five to ten minutes just to relax there.
keep the arm very still and then I'll review the situation when I come back
okay let me just review the arm here
I can see you've got some localized inflammation here from the histamine.
That's what we were looking. Just going down
the rest
just ensuring there's further localized inflammation
and there doesn't seem to have been a reaction to those allergens. wonderful so the final step
for me is just to demarcate the localized inflammation there
and just take a sample with the tape
wonderful we have the sample there right
that is everything for today your first patch
allergy test now if you have any further problems later in the day
you need to speak to your doctor if possible. just tell him you've had a patch allergy test
and then take it further but you should be absolutely fine, it's been at least 10 minutes
and we only have the histamine reaction there so that's everything. thank you for coming in today,
we will get the results emailed to you as soon as we can
