Mutated Citrullinated Vimentin (MCV) Antibody
Labcorp
Not offered
This test is used to help diagnose rheumatoid arthritis (RA) by detecting specific antibodies. It's often used alongside other markers like rheumatoid factor and anti-cyclic citrullinated peptide (CCP). While MCV antibody is slightly less specific than CCP, it offers a bit higher sensitivity, improving RA diagnosis by 5-10% when combined with CCP. A positive MCV antibody test also indicates a more severe form of the disease and a greater likelihood of joint damage over time.
Mycoplasma pneumoniae Antibody (IgG)

Myeloperoxidase (MPO)
Myeloperoxidase (MPO) is an enzyme produced by white blood cells involved in inflammation and oxidative stress. Elevated MPO levels are associated with increased risk of cardiovascular disease and may indicate ongoing vascular inflammation.
- Myeloperoxidase (MPO) An enzyme released by certain white blood cells during inflammation; also studied as a marker of cardiovascular plaque instability.

Myeloperoxidase (MPO) Antibodies
This test measures antibodies against myeloperoxidase (MPO), a protein found in certain white blood cells. MPO antibodies are associated with some autoimmune vasculitis disorders and may help evaluate inflammation and damage affecting blood vessels and organs.
- Myeloperoxidase (MPO) Antibodies Also called p-ANCA/MPO antibodies — autoantibodies associated with certain forms of vasculitis (blood vessel inflammation).

Myoglobin
Myoglobin is a protein found in heart and skeletal muscle that is released into the bloodstream following muscle injury. It is used to help detect muscle damage, including heart attacks and rhabdomyolysis.
- Myoglobin A protein released from damaged muscle tissue, including heart muscle. Rises quickly after injury, though it's not specific to the heart.

Neurofilament Light Chain
Quest
Not offered
This tests measures level of neurofilament light chain (NfL) protein in the blood or cerebrospinal fluid. Elevated levels of NfL are indicative of neuronal damage and are used as a biomarker for various neurological conditions, including multiple sclerosis, amyotrophic lateral sclerosis (ALS), Alzheimer’s disease, and other neurodegenerative disorders. This test provides valuable insights into disease progression, prognosis, and response to treatment in patients with neurological diseases.
- Neurofilament Light Chain A protein released when nerve cells are damaged. An emerging marker studied in neurological conditions like multiple sclerosis and neurodegenerative disease.
Neurofilament Light Chain (NfL), Plasma
Labcorp
Not offered
Neurofilament light (NfL) is an intermediate filament protein found specifically in the neuronal cytoskeleton. It can be released into the extracellular space through axonal degradation, and it has been shown that varying NfL levels are an indicator of neuroaxonal damage, irrespective of the cause, and can therefore be associated with a variety of neurological diseases such as multiple sclerosis, amyotrophic lateral sclerosis, frontotemporal dementia, or Alzheimer's disease, as well as acute situations such as traumatic brain injury and others. NfL is thus considered a promising biomarker for, disease activity, progression, prognosis, and monitoring effectiveness of therapies. As NfL can be measured in both cerebrospinal fluid (CSF) and blood, it holds great potential for routine clinical use.

- HDL Size Measures the average size of your HDL ('good' cholesterol) particles, used alongside particle number for a more detailed cardiovascular risk assessment.
- LDL Size Measures the average size of your LDL ('bad' cholesterol) particles; smaller, denser particles are considered more likely to contribute to artery plaque.
- LP-IR Score Lipoprotein Insulin Resistance Score — a composite score derived from lipoprotein particle measurements that estimates insulin resistance.
- Large VLDL-P Counts the largest VLDL particles, which carry a high amount of triglycerides and are associated with greater cardiovascular risk.
- VLDL Size Measures the average size of your VLDL particles, used alongside particle number for a more detailed cardiovascular risk assessment.
- HDL Large
- LDL Particle Number LDL particle number — counts your actual LDL ('bad' cholesterol) particles rather than just the cholesterol they carry, often a stronger cardiovascular risk indicator than standard LDL cholesterol.
- LDL Small
