• Mercury Measures mercury levels in your blood, used to assess exposure to this toxic heavy metal, often from certain fish or environmental sources.
• Mercury, 24 Hour Measures the total mercury passed in your urine over 24 hours, used to assess exposure mainly to elemental and inorganic mercury.

• Mesquite Tree (t20) IgE Measures IgE antibodies to mesquite tree pollen to check for allergic sensitization that may explain spring hay fever or asthma symptoms.
• Metamyelocytes The absolute number of metamyelocytes, immature white blood cells normally found in bone marrow, in your blood as part of a differential count.
• Metamyelocytes (%) The percentage of your white blood cells that are metamyelocytes, an immature white blood cell normally confined to the bone marrow.
• Methylenetetrahydrofolate Reductase (MTHFR), DNA A genetic test for variants in the MTHFR gene, which affects how your body processes folate and can influence homocysteine levels.
• Methylmalonic AcidMMA A compound that builds up when vitamin B12 is deficient. A more sensitive marker of B12 status than a B12 blood level alone.

• Mitogen-NiL A control value in the QuantiFERON-TB Gold Plus test showing that your immune cells can respond normally, so the TB result can be trusted.
• MLH1 Looks for inherited changes in the MLH1 gene, a DNA mismatch repair gene, as part of testing for Lynch syndrome.
• Monocytes The number of monocytes, white blood cells that help fight infection and clear damaged cells, in your blood.
• Monocytes (%) The percentage of your white blood cells that are monocytes, cells that help fight infection and clear damaged tissue.
• Monomeric Prolactin The active, single-molecule form of prolactin, distinguished from macroprolactin (a larger, less active form) to clarify the true cause of an elevated prolactin result.
• Monounsaturated, Total The combined serum level of monounsaturated fatty acids, such as oleic acid, giving an overview of this fat group in your blood.
• Mosquito (i71) IgE Measures IgE antibodies to mosquito proteins to check for allergic sensitization that may relate to unusually strong reactions to mosquito bites.
• Mountain Cedar (t6) IgE Measures IgE antibodies to mountain cedar pollen to check for allergic sensitization that may explain winter hay fever or asthma symptoms.
