"The simple DNA genetic test kit, pictured left, is easy to use, painless, bloodless, and takes only a few minutes to complete. You simply swab your cheek with a small brush. It is perfect for infants, children, and adults. Results are ready in just a few days after testing. Results are confidential and private. For people who wish for their results to remain private, and not appear in their medical records, direct home testing is a good option". Sandra Thomas, President, AHS |

Blood
testing
to
check
your
iron
storage
status,
known
as
a
complete
iron

is
available.
If

Genetic
Labs
Performing
DNA
Testing
for
Hereditary
Hemochromatosis
This
is
the
latest
technology
in
medicine
which
will
quickly
and
accurately
determine
if
you
have
the
HFE
(HH)
mutation
for hereditary
hemochromatosis
(HH).
This
test
can
help
confirm
the
diagnosis
of
hereditary
hemochromatosis
in
the
presence
of
elevated
transferrin saturation
percentage
and
elevated
serum
ferritin.
In
some
cases,
this
test
can
help
the
doctor
to
avoid
the
traditional
(and
invasive)
liver
biopsy
for
the
patient
when
the
ferritin
is
only
slightly
elevated
(early
diagnosis)
and
no
other
signs
of
liver distress
are
evident
such
as
elevated
liver
enzymes.
Another
significant
use
of
the
DNA
test
is
screening
other
family
members for
their
genetic
risk
once
one
family
member
has
been
identified
with
the
mutation.
This
is
particularly
useful
in
children to
identify
them
at
an
early
age
so
that
the
pediatrician
can
monitor
the
child
throughout
childhood
for
iron
storage. AHS
advocates
newborn
screening
with
the
genetic
test
to
have
the
earliest
possible
awareness
of
this
mutation
being
present
so that
the
life
of
the
child
may
be
protected
through
close
monitoring
by
the
pediatrician. Sandra Thomas
believes
that
everyone
should have
the
genetic
(DNA)
test,
whether
or
not
they
have
a
family
history
of
HH
or
symptoms
of
HH.
Only testing
can
show
you
for
sure
if
you,
or
your
family,
is
at
risk
for
HH
and
if
the
HH gene
mutation,
known
as
the
HFE
mutation,
is
present
in
your family gene pool.
Sandra Thomas, President/Founder of the American Hemochromatosis Society, discusses iron overload and hemochromatosis with the "Iron King", William Crosby, MD. Dr. Crosby was a pioneer in the field of iron overload/hemochromatosis research and was a good friend to the Thomas family during Sandra's mother's battle with hemochromatosis.
Warning: The
doctors
on
the
Board
of
Directors
of
The
American
Hemochromatosis
Society
state
that
transferrin
saturation
percentage
greater
than
40% and
serum
ferritin
greater
than
150ng/mL could
indicate
clinical
iron
overload/iron
storage
in
the
body
and
treatment
with
phlebotomy (bloodletting)
should be considered regardless
of
DNA
test
results.
This
means
that
patients'
treatment
should
not
be
based
on
genetic
test
results
alone whether
positive
or
negative.
The
DNA
test
is
a
powerful
tool
to
help
us
find
people
at
risk;
85-98%
of
patients with
clinical
iron
overload
have
the
hemochromatosis
mutations,
however,
the
most
important
point
to
remember
is
that
excess
iron
needs to
be
evaluated
and
treated.
William
Crosby,
MD, (see photo above)
the late well
known
hemochromatosis
physician and researcher, declared
that
if
a
patient
has
demonstrated
excess iron
then
they
are
in
danger
of
organ
damage
and
premature
death.
Patients
should
be
aggressively
(usual
rate
is
weekly
or twice
weekly depending on the stage of the disease)
treated
with
phlebotomy
(bloodletting
identical
to
blood
donation)
for
excess
iron!
Treatment frequency can be adjusted for individual patients with special circumstances (elderly, other medical problems, etc.) See
AHS
guidelines

Sandra is a "silent carrier" (heterozygote) of the cys282 HFE gene mutation for hereditary hemochromatosis (HH).
WARNING: HLA-typing
is
NOT
the
same
as
DNA
genetic
testing.
HLA
typing
is
an
outdated
form
of
testing
that
does
not
identify the
gene
mutation
for
hereditary
hemochromatosis.
Make
sure
that
you
and
your
doctor
are
not
ordering
HLA
typing,
but
rather genetic
testing
by
PCR
for
the
HFE
mutation
(cys282
and
his63)
on
the
short
arm
of
chromosome
6. A few labs also offer testing for the 65C gene mutation, but most labs test only for the cys282 and his63 gene mutations.

Other
Considerations
and
Thoughts
for
You:
*If
you
use
a
doctor
for
testing
(rather
than
doing
it
yourself),
do
not
simply
ask
your
doctor
to
test
you
for
iron
overload/hereditaryhemochromatosis,
but
rather
ask
for
these
blood
tests
by
name:
serum
iron,TIBC
(total
iron
binding
capacity),
and
serum
ferritin
(blood
taken
in
the
doctor's
office
from
your
arm
not
your
finger.)
Remember
hematocrit
(hct
)and
hemoglobin
(hgb)
are
not
tests
to
confirm
HH.
If
you
want
the
fastest
and
easiest
way
to
find
out
if
you
have
hemochromatosis,
simply
call
HealthCheckUSA.com
and
order
the
tests
yourself.
You'll
have
your
results
in
a
few
days.
And,
it
is
completely
private.
You
can
get
DNA
test
results
from
GeneTrack.
*Percent
of
saturation
is
calculated
by
dividing
the
numerical
result
of
the
serum
iron
by
the
numerical
result
of
the
TIBC.
A
percent
of
saturationgreater
than
40%
(>40%)
and/or
a
serum
ferritin
greater
than
150
ng/ml
(>150ng/ml)
is
suggestive
of
HH
and
should
be
further
investigated
by
a
qualified
physician.
*DNA
(genetic)
testing
by
a
lab
which
tests
for
both
HFE
mutations
(cys282
&
his63)
can
help
confirm
the
diagnosis
in
the
presence
of
high
iron
levels
or
determine
genetic
risk
for
HH
in
patients
with
normal
iron
levels
who
may
be
at
high
risk
of
storing
iron
in
the
future.
Patients
who
have
normal
iron
levels
but
who
are
positive
for
the
HH
mutations
should
be
put
in
a
surveillance
program
by
their
doctors.
If
you
wish
to
simplify
the
process,
genetically
test
yourself
using
a
DNA
genetic
test
kit.
Call
GeneTrack.com
(www.hemochromatosisdna.com)
or

number:
1-877-714-6356.
*Always
get
copies
of
your
own
lab
results
and
medical
records
and
read
them
yourself.
Keep
a
master
set
of
medical
records
in
a
home
medical
file;
never
give
out
your
original
master
set
records,
make
copies
instead, to give to doctors you may visit for additional opinions..
*Always
consider
getting
a
second
opinion or
even multiple,
medical
opinions,
especially
if
you
have
an
advanced
case
of
HH
with
serious
medical
complications. You may have to travel out of town, but it will be worth it. Contact AHS for the names of top experts around the country.
*Avoid
eating
or
handling
raw
seafood,
especially
if
you
have
liver
disease
due
to
HH
(or
any
cause)
cooked
seafood
is
fine;
do
not
take
vitamin
C
supplements
(natural
sources
such
as
orange
juice
are
fine);and
do
not
take
iron
supplements
or
vitamins
with
iron;
do
not
cook
food
in
cast
iron
cookware.
*Do
not
eat
a
diet
void
of
iron,
it
is
unpleasant,
unhealthy,
and
you
will
end
up
weak!
(one
patient
reported
eating
nothing
but
water
and
cottage
cheese
the
first
two
weeks
after
her
diagnosis
she
was
so
fearful
of
eating
anything
with
iron
in
it).
Remember
our
diet
motto: “All
take
heed,
you
may
eat
the
food
that
you
need,
but
be
willing
to
bleed!”
*Aggressive
bloodletting
(therapeutic
phlebotomy/TP)
should
be
the
treatment
of
choice
with
1
unit
of
blood
removed
usually
once
or
twice
a
week,
until
serum
ferritin
is
less
than
20ng/ml
(<20)
and
then
maintain
it
between 20 and 50 for life, then
performing
3
to
4
treatments
per
year
for
the
lifetime
of
the
patient.
Treatments
should
be
individualized
to
each
patient,
taking
into
consideration
the
age,
size,
weight,
and
stage
of
HH
of
the
patient,
so
that
frequency
of
treatments
and
amount
of blood removed can be adjusted accordingly.
*Liver
biopsy
may
be
necessary
to
determine
extent
of
advanced
liver
disease
if
liver
function
tests
(LFT’s)
are
significantly
elevated
and
there
are
signs
of
liver
distress.
Discuss
the
need
for
this
procedure
carefully
with
your
physician.
Those
with
early,
asymptomatic
HH
with
normal
LFT’s, probably will be able to forego this invasive, and potentially
risky procedure. The earlier the diagnosis, the less chance you’ll
need a liver biopsy, so early screening is important. If you do have
a liver biopsy, request that it be done with “guidance” such
as ultrasound or CT and don’t take aspirin type medications
a week prior to the procedure. Liver biopsy is used to diagnose,
not screen for, primary liver cancer (PLC) . Patients at high risk
for PLC should be
screened every three to six months with alpha fetoprotein and PIVKA-II
blood tests for the rest of their lives. If you refuse to have a liver biopsy, you can still be treated. If your doctor refuses to treat you without a liver biopsy being done first, find another specialist who will.
*Warn
all
family
members
to
be
tested
and
keep
a
computer
file
of
family
members’ results.
Don’t
forget
the
elderly
and
the
kids
when
screening
family
members.
Remember,
men,
women, and children can get iron overload/HH.

Hemochromatosis: Treatment
Have you ever donated blood?
If you have, then you know exactly
what the treatment is for hemochromatosis!
Josephine Bogie Thomas donates blood to control her advanced stage hereditary hemochromatosis.
It took 85 treatments to get her "de-ironed" with a total 106 treatments in her lifetime.
These phlebotomy treatments done at a local blood bank added another 16 years to her life!
Treatment, also known as therapeutic phebotomy (TP), or "bloodletting"
can take place in several locations--a doctor's office, a hospital blood bank, or a community blood bank. Insurance often covers doctor's office and hospital treatments, but not blood banks. If you are paying out of pocket, blood banks would be your best choice since some blood banks will remove the blood for free and use the blood as donor blood. These blood banks are approved by the FDA and have applied for and received a "variance" to use hereditary hemochromatosis (HH) blood as donor blood.
Regardless of where you are treated, find a nurse/tech whom you like and who takes the blood in a comfortable fashion. "Bloodletting" as it is sometimes called, is an "art" and you want to find someone who has the "talent" to do it well. The truth is, some people are better at taking blood than others, so when you find that someone "special", you need to find out his/her name and schedule and make sure that your treatment coincide with their hours. Be sure to call the blood bank first, for instance, to make sure that they are there for their regular shift and wait until they are available. This is a handy tip that will make your treatment experience a positive one.
Be sure to eat well before and after your treatment, and also drink plenty of fluids before and after treatment. Until you are used to the procedure, take someone with you to drive and give you support, so that you are more relaxed about your experience. If it is your first time, be sure to let the staff know any concerns or fears that you might have. This will help them to be more sensitive to your needs.
If you are afraid of needles, you are not alone! Many patients feel this way, but with experience and a supportive staff, they overcome this fear even in the most extreme cases and proceed on with their treatment. If your anxiety is great, let your doctor know. Don't suffer in silence. Your doctor can prescribe a mild sedative that can "take the edge off" of your anxiety and help you to help yourself through your treatment schedule.
Most patients want to know how many treatments they will need. That number will depend on what stage of the disease the patient has. If it is an early stage diagnosis, they may only need a few treatments before being "de-ironed". Other patients with more advanced cases, for instance, a ferritin level greater than 1,000, may need dozens of treatments before reducing the iron storage burden to the level it needs to be (a ferritin of 20 is the usual goal, then keep the ferritin between 20 and 50 for the rest of the patient's life).
The
usual
frequency
of
the
treatments
are
once
a
week
and
in
advanced
cases,
sometimes
twice
a
week.
Based
on
various
factors,
age,
health,
and
weight/size,
some
patients
may
be
treated
less
frequently,
for
instance,
every
other
week,
or
once
a
month.
In
general,
though,
if
the
patient
has
a
high
ferritin
(500
or
greater)
and
is
basically
in
good
health
otherwise,
a
minimum
of
once
a
week
is
advised.
The weekly treatments will continue until the ferritin reaches 20. At this point, the patient is "de-ironed". The patient can now reduce the treatments to about three to four times a year. This schedule will vary from patient to patient. Some patients need to be treated once a month indefinitely, whereas other patients only need one or two treatments a year. Some of this frequency will depend on the patient's diet and how strict they are with themselves concerning iron intake through their diet.
The treatment is usually simple and easy. It should not be a source of great anxiety or discomfort. If it is, then it is time to talk with the doctor, change doctors, change blood banks, or get counseling concerning what is bothering the patient. Treatment is key to saving the patient's life in advanced cases, and to preventing organ damage and premature death in earlier stage cases.
Many patients report feeling so much better after each treatment. Some are treated during their lunch break. It is normal to feel tired a few days after the treatment, but remember, each time you give blood, you are reducing the iron stores in your body! Don't give up! Each treatment is bringing you closer to saving your own life!
