The acronym MAR stands for mixed antiglobulin reaction. The test is used to diagnose imunological infertility, which means that antisperm antibodies are present that prevent conception from taking place. Antibodies in blood, semen or cervical mucous coat the surface of the sperm, which impairs sperm transport and ultimately fertilisation of the ovum.

Margaric acid is also known as heptadecanoic acid. It is a 17-carbon saturated fatty acid (17:0). Food sources mainly include milk and dairy products, though it can be endogenously made as well.

Most research in fatty acid metabolism has focused on even-chain fatty acids since they represent >99% of total human lipid concentration. For years, it had been concluded that odd chain saturated fatty acids (OCSFAs) were of little significance and used only as internal standards in laboratory methodology. However, there is now a realization that they are, in fact, relevant and important physiologically.

Matrix Metalloproteinase 9 (MMP-9), also known as gelatinase B, is a critical enzyme in the human body that plays a vital role in remodeling the extracellular matrix, the network of proteins and other substances surrounding cells. It belongs to a larger family of enzymes known as matrix metalloproteinases, which are responsible for breaking down various components of the extracellular matrix.

MMP-9 specifically targets collagen and gelatin, important structural proteins in tissues. By breaking down these proteins, MMP-9 aids in processes like wound healing, tissue repair, and angiogenesis (the formation of new blood vessels). This makes it an essential player in normal physiological processes. However, MMP-9's activity isn't always beneficial; its overactivity or dysregulation is linked to various diseases.

The relative index represents the ratio of CKMB to the CK, total. Relative index = CK-MB, in ng/mL ÷ CK, total, U/L x 100. Due to the different units measured (ng/mL for CK-MB vs. U/L for CK, total), this does not represent a true percentage and is, therefore, called a “relative index.” Currently, a relative index of ≥5.0% suggests the MB may be myocardial in origin. The relative index may be of particular value in patients who have an elevated CK, total due to trauma or surgery.

Both an elevated CK-MB and Relative Index are suggestive of Myocardial Infarction.

Mead Acid (plasma) is a marker for overall, essential fatty acid status. 

Mean cell volume indicates the average volume of red blood cells in the body. It is often measured as a part of the red blood cell indices in a comprehensive blood count test. The results of the red blood cell indices will tell a healthcare professional whether or not anemia is present and, if so, what type it is.

Mean Corpuscular Hemoglobin (MCH) refers to the average amount of hemoglobin contained in a single red blood cell. Hemoglobin is a vital protein in the blood responsible for transporting oxygen from the lungs to the body's cells.

MCHC stands for mean corpuscular hemoglobin concentration. MCHC is part of the red cell indices, together with MCH and MCV. Those parameters reflect the size and hemoglobin content of red cells. They have traditionally been used to aid in the differential diagnosis of anemia.

The mean particle size in a lipid or metabolic profile provides important information about the type of lipoprotein particles present in the blood, which has implications for cardiovascular risk and overall metabolic health. This marker is increasingly being recognized as a crucial component in comprehensive cardiovascular risk assessment.

Mean platelet volume (MPV) is a calculation that indicates the average size of platelets in the blood. This measurement is typically done during a comprehensive blood count. An abnormal MPV is not, in it of itself, an indication of disease or disorder. MPV scores are compared against other types of blood counts to give a healthcare professional more information about a potential medical issue.

Mean RBC Iron is a specialized marker that can be found on some Complete Blood Count (CBC) panels. This marker measures the average amount of iron contained within the red blood cells (RBCs) in a given sample of blood. Iron is a crucial component of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body. Understanding the average iron content in red blood cells helps doctors assess whether there's an appropriate amount of iron available for hemoglobin production, which is essential for effective oxygen transport. If the Mean RBC Iron levels are unusually high or low, it might indicate an iron disorder, such as iron deficiency anemia or hemochromatosis, a condition where too much iron builds up in the body. These insights are particularly useful in diagnosing and managing conditions related to iron metabolism and anemia, thereby guiding treatment decisions to ensure the proper management of these conditions.

Mean RBC Iron Concentration on a Complete Blood Count (CBC) panel refers to the average concentration of iron found within the red blood cells (RBCs) circulating in your bloodstream. This measurement, often reported as part of a broader test called "Mean Corpuscular Hemoglobin Concentration" (MCHC), provides critical insights into how much hemoglobin, the oxygen-carrying component of red blood cells, is present relative to the size of these cells. A normal range of MCHC suggests that your red blood cells have a healthy amount of hemoglobin, which is essential for efficient oxygen transport throughout the body.

The marker Mean RBC Volume refers to the average volume of red blood cells (RBCs) in your blood, and it is expressed in femtoliters (fL). This measurement is also known as Mean Corpuscular Volume (MCV). It's an important diagnostic tool because it helps in the assessment of various types of anemia and other health conditions. A normal MCV falls within a specific range, but variations can indicate different issues: a higher MCV might suggest macrocytic anemia, often due to vitamin B12 or folate deficiency, whereas a lower MCV could indicate microcytic anemia, commonly due to iron deficiency. By measuring how big or small your red blood cells are on average, healthcare providers can gain insights into your overall health, particularly concerning your blood's ability to carry oxygen and nutrients. If your MCV is outside the normal range, it prompts further investigation to determine the underlying cause, which might involve looking at other markers on the CBC or additional tests.

The measles virus belongs to the Paramyxoviridae family, which also includes parainfluenza virus serotypes 1-4, mumps, respiratory syncytial virus (RSV), and metapneumovirus. Measles is highly contagious, primarily transmitted through direct contact with aerosolized droplets or respiratory secretions from infected individuals.
