From my research, there are no simple or reliable or accurate tests for mercury poisoning that is chronic. Mercury ends up in deep tissues, organs , and brain where you can't measure it easily.
I would suggest you read Amalgam Illness, by A.C. Hall. I would recommend taking DMSA and ALA every 4 hours for three days,rest 4 days, repeat. There is no better protocol, but quite a few that are worse.
Chlorella may contain mercury as it comes from the sea.
I just tried some Glucosamine (which is made froms shellfish) and it made me depressed and toxic.

I've been using chlorella daily for
more than 20 years, and I'm in
perfect health. Don't let people
frighten you away from it.

Chlorella is an algae, like spirulina. The best chlorella grows
in freshwater lakes like Klamath
Lake in Oregon. Lakes in the remote
islands of Japan are also top-notch
sources of pure chlorella, as well
as Chinese mountain lakes near the
border of Nepal.

I would not want to eat any chlorella that came from New York
Harbor or the Interstate Waterway.
But the very best superfood and
supplement makers use clean,
freshwater chlorella.

I take at least two superfoods that
contain chlorella every day of my
life. Pure Synergy uses chlorella
from Klamath Lake. Greens+ uses
Japanese Chlorella. Ron Teeguarden
of Dragon Herbs uses Chinese chlorella in his superb superfood,
Tonic Alchemy. And Dr. Jon Barron
has opted to put chlorella in his
brand-new superfood. Dr. Joseph
Mercola's chlorella capsules from
from lakes on the out-islands of
Japan.

I also eat cilantro every day in
the form of cilantro pesto. I began
eating a spoonful each day, three
years ago when I had 8 amalgam
fillings removed. I have had NO
bad reactions from either the
cilantro or the chlorella. Indeed,
I'm sure that I'm much healthier
because of them.

Someday soon, I'm going to post a
lot of positive quotes about chlorella, from the above-mentioned
men, and others. Until then, If I
were you, I'd take Rokybird's
suggestions about the two chelation
protocols she describes. And as for
cilantro and chlorella, you will
have to trust your intuition. I'm
glad I did.

Good luck on your healing quest!

Blessings,

In my experience with chelation so far DMPS and DMSA hit the mercury the best.IV chelation is harsh,but it works.You might wanna get in a sauna or put on some detox foot pads after doing IV chelation.You don't want the metal to be reabsorbed and that's why you need to get it out through your skin.Their's only so many times you can go to the bathroom.Those detox foot pads really do work.When I'm having horrific detox reactions I just put those on, the toxins start going in the pads and I feel better.I have problems like acid reflux when Im detoxing, and it goes away when I put the pads on to get the toxins out of my body.Another product I use in a similar fashion is PCA RX.PCA RX engulfs the toxins and protects me from the detox reactions.These products detoxify mercury in their own right, but they also help with detox reactions from DMPS and DMSA.Some people say IV chelation is too harsh and to use to the Andy Cutler method.As long as your digestive system is in order, and you are able to absorb the chelator this method is fine.The only form of chlorella that worked for me was NDF.I've never tried clay baths, but I've heard from reliable sources that they are effective.My advice to you is to use all the products.Before you start I think you should support yourself nutritionally with something like Life Extention MIX,Life Extention Super Booster, and Vitamineral Green.Oh yeah, mercury inhibits the enzymes that are responsible for detoxification and makes you succeptible to accumulating other metals like lead,uranium,cadmium,and arsenic.Test for mercury with an IV DMPS challenge and test for lead and cadmium with an IV EDTA challenge.Sometimes,the metal shows up in a hair mineral analysis.Test with both methods.Sometimes, the metal doesn't show up the first times you do the IV chelation challenge. So do it multiple times.I'd suggest finding a DAN doctor or doing the Amy Yasko protocol.The chelators,foot pads, pca rx and all this stuff are great ,but doing the Dan or Yasko protocol will help your body naturally detoxify, repair damage the mercury did, and allow the chelators to work much better.For perfect health you need to detox the mercury and fix the damage it did with one or even a combo of these protocols.
