What is gonorrhea?

Gonorrhea is a sexually transmitted disease (STD) caused by infection with the Neisseria gonorrhoeae bacterium. N. gonorrhoeae infects the mucous membranes of the reproductive tract, including the cervix, uterus, and fallopian tubes in women, and the urethra in women and men. N. gonorrhoeae can also infect the mucous membranes of the mouth, throat, eyes, and rectum.

How do people get gonorrhea?

Gonorrhea is transmitted through sexual contact with the penis, vagina, mouth, or anus of an infected partner. Ejaculation does not have to occur for gonorrhea to be transmitted or acquired. Gonorrhea can also be spread perinatally from mother to baby during childbirth.

People who have had gonorrhea and received treatment may be reinfected if they have sexual contact with a person infected with gonorrhea.

Nervonic acid is a monounsaturated fatty acid. Nervonic acid has the longest carbon chain of all monounsaturated fatty acids. It is found in highest concentrations in nerve membranes, particularly in myelin sheaths, which are sleeves of fatty tissue that protect your nerve cells.

Nervonic acid (NA) is an omega-9 MUFA with a 24-carbon backbone and one double bond (24:1n9). It is a very important fatty acid in the white matter of the brain and is responsible for nerve cell myelin biosynthesis. There are small amounts of NA in cooking fats, vegetable oils and borage oil. It can also be synthesized in the body by elongating oleic acid (which is essentially desaturated stearic acid). NA is essential for the growth and maintenance of the brain and peripheral nervous tissue enriched with sphingomyelin.

Neurofilament proteins are vital structural components of nerve cells, helping to maintain their shape and function. Of these, neurofilament light chain (NfL) has emerged as a clinically important biomarker. When neurons are damaged or undergoing degeneration, NfL is released into the cerebrospinal fluid (CSF) and blood, where it can be measured. Elevated NfL levels are a highly sensitive indicator of neuroaxonal injury, though it is important to note that NfL is not specific to any single disease—it reflects neuronal damage from a variety of causes.

Neuron-specific enolase (NSE) is an enzyme that is found in the cytoplasm of neurons and neuroendocrine cells. The production of NSE occurs late in neural differentiation, thus making NSE an index of neural maturation.

Neuron-specific enolase (NSE) is a key biomarker predominantly found in neurons and neuroendocrine cells, making it highly valuable for clinical diagnostics and monitoring neurological and neuroendocrine disorders. NSE is a glycolytic enzyme that plays a crucial role in the process of glycolysis, helping to convert glucose into energy. Due to its specificity, elevated levels of NSE in the blood or cerebrospinal fluid (CSF) are often indicative of neuronal damage or neuroendocrine tumors. Clinically, NSE is extensively used as a tumor marker for small cell lung cancer (SCLC) and neuroblastoma, where its elevated levels correlate with tumor burden, disease progression, and patient prognosis.

NLR (Neutrophil to Lymphocyte Ratio) is a biomarker that can be used as an indication of subclinical inflammation. NLR is a calculation based on the Absolute Neutrophil Count divided by the Absolute Lymphocyte Count determined by the peripheral blood CBC differential. This calculation, according to recent literature, is useful in assessing the likelihood of severe progression of disease in SARS-CoV-2 positive patients.

Neutrophil Antibody, Flow Cytometry - Neutrophil Antibody has been observed with neonatal alloimmune neutropenia, autoimmune neutropenia, transfusion reactions, and drug-induced neutropenia.

The "Neutrophil Antibody, Flow Cytometry - Neutrophil Antibody" test on a panel from Quest Diagnostics is a specialized diagnostic tool used to detect antibodies that target neutrophils, which are a type of white blood cell crucial for our immune defense against infections. Neutrophil antibodies can lead to various conditions, including autoimmune neutropenia—where the immune system mistakenly attacks and destroys neutrophils, reducing the body's ability to fight off infections. This test is particularly useful in diagnosing immune-related neutropenia, monitoring the severity of the autoimmune response, and guiding treatment decisions in conditions where neutrophil antibodies may be involved.

What Are Neutrophils?

Neutrophils are the most abundant white blood cells, essential for immune defense. They are produced in the bone marrow and travel through the bloodstream and tissues to combat infections.

As phagocytic cells, neutrophils engulf and destroy bacteria, viruses, and other invaders at infection sites. They also play a role in the inflammatory response, helping the body react to allergens and injuries.

Neutrophils are clear in color and typically spherical when at rest, but they change shape to fight infections effectively.

What Are Neutrophils?

Neutrophils are the most abundant type of white blood cell (WBC) in the human body and are critical to your immune system's function. As phagocytic cells, their primary role is to engulf and destroy harmful invaders like bacteria and viruses, especially at the site of an injury or infection.

Beyond their role in combating infections, neutrophils are also involved in the body’s inflammatory response. They respond to allergens, injuries, or infections by releasing enzymes and signaling other immune cells, which contributes to inflammation—a natural process that helps protect and heal the body.

With their dual role in immunity and inflammation, neutrophils are indispensable for maintaining your overall health and defending against a wide range of pathogens.

Synovial fluid analysis includes a differential cell count, which identifies and quantifies the different types of white blood cells present in the fluid. Neutrophils are one of the cell types counted in this differential analysis. It is a critical parameter that aids in the assessment of joint health.

An elevated percentage can signal inflammation or infection within the joint, helping guide diagnosis and treatment decisions.
