How do you test for mercury?
What medical testing is used to detect mercury exposure? The most commonly accepted methods of assessing mercury exposure are to test urine or blood. Both tests usually measure levels of total mercury (elemental, inorganic and organic).
What is normal level of mercury in blood?
Small amounts of mercury are often present in blood, primarily due to variable amounts of methylmercury in the diet. Typical levels of total mercury in blood range up to about 5 micrograms/Liter (mcg /L).
What is a high mercury level in blood?
According to the Mayo Clinic, blood mercury levels of 0 to 9 nanograms per milliliter (ng/mL) are normal and do not present a concern. A level of 10 to 15 ng/mL indicates mild exposure. Anything over 50 ng/mL may indicate heavy exposure to organic mercury.
What color tube is mercury?
Royal blue-top
Royal blue-top (EDTA) tube; submit original tube.
How much mercury is toxic from a thermometer?
about 0.5-0.6 grams
Mercury can be poisonous in certain situations. Most oral and rectal thermometers contain about 0.5-0.6 grams of mercury. The main health problems from mercury are from the vapors. These are produced at room temperature and especially when mercury is heated.
Can you get mercury poisoning from a thermometer?
Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
Does mercury show up in blood tests?
Blood is primarily tested to detect the presence of methyl mercury. Other forms of mercury (metallic and inorganic) can also be detected in the blood, but the amount present will decrease by half about every 3 days as the mercury moves into organs such as the brain and kidneys.
What gets rid of mercury?
The traditional treatment for mercury poisoning is to stop all exposures. In many cases, chelation therapy is also used. This involves giving a medication (the chelator) which goes into the body and grabs the metal (chelos is the Greek word for claw) then carries the metal out of the body, usually into the urine.
Is mercury poisoning permanent?
When detected early, mercury poisoning can be halted. Neurological effects from mercury toxicity are often permanent. If you suspect sudden mercury poisoning, call the Poison Control Center at 800-222-1222.
What are yellow top tubes used for?

What if I touched mercury from a thermometer?
MERCURY EXPOSURE If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
Do thermometers still use mercury?
Although mercury thermometers have been mostly phased out of daily home use, the tool, which was invented in the 1700s by Gabriel Daniel Fahrenheit, remains a standard measuring device for many industries, including regulating the temperature of a chemical concoction being made in an industrial lab, and monitoring the …
