Ab (Antibody)

Definition
An antibody is a protein produced by the immune system in response to foreign substances (antigens) like bacteria, viruses, or toxins. Antibodies help neutralize these invaders.
Term

Ag (Antigen)

Definition
 An antigen is any substance that triggers an immune response in the body, such as bacteria, viruses, or other foreign particles. Antigens stimulate the production of antibodies.
Term

CA, Ca (Cancer)

Definition
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. It can develop in any organ or tissue.
Term

CIS (Carcinoma In Situ)

Definition
Carcinoma in situ is a term used to describe cancer cells that are in the place where they first formed and have not spread to surrounding tissues. It is an early-stage cancer.
Term

DCIS (Ductal Carcinoma In Situ)

Definition
DCIS is a non-invasive type of breast cancer where abnormal cells are found in the lining of a breast duct but have not spread beyond the duct. It is an early form of breast cancer.
Term

ELISA (Enzyme-Linked Immunosorbent Assay)

Definition
ELISA is a laboratory test used to detect antibodies in the blood, commonly used to diagnose infections, such as HIV, or monitor immune responses.
Term

HL (Hodgkin Lymphoma)

Definition
Hodgkin lymphoma is a type of cancer that begins in the lymphatic system and is characterized by the presence of abnormal cells called Reed-Sternberg cells. It affects the immune system's ability to fight infection.
Term

HZ (Herpes Zoster)

Definition
Herpes zoster, also known as shingles, is a viral infection caused by the reactivation of the varicella-zoster virus, which causes chickenpox. It results in a painful rash.
Term

IgA (Immunoglobulin A)

Definition
IgA is an antibody that plays a crucial role in mucosal immunity, providing protection to body surfaces such as the respiratory and digestive tracts.
Term

IgD (Immunoglobulin D)

Definition
IgD is a type of antibody that is present in small amounts in the blood and is involved in the activation of immune responses, particularly in the development of B cells.
Term

IgE (Immunoglobulin E)

Definition
gE is an antibody that is involved in allergic reactions and protects against parasitic infections. Elevated IgE levels are often seen in individuals with allergies.
Term

IgG (Immunoglobulin G)

Definition
IgG is the most common type of antibody in the blood and body fluids, providing long-term protection against bacteria and viruses. It plays a critical role in the immune response.
Term

IgM (Immunoglobulin M)

Definition
lgM is the first antibody produced in response to an infection. It provides early defense while the body prepares to produce more specific antibodies like IgG.
Term

IG (Immunoglobulin)

Definition
Immunoglobulin is a type of antibody produced by the immune system to help fight infections. There are different types of immunoglobulins, each playing a unique role in the immune response.
Term

LE (Lupus Erythematosus)

Definition
Lupus erythematosus is an autoimmune disease where the immune system attacks healthy tissue, causing inflammation, pain, and damage to various parts of the body, including skin, joints, and organs.
Term

MET (Metastasis)

Definition
Metastasis refers to the spread of cancer cells from the original (primary) site to other parts of the body. This process makes cancer more difficult to treat and more dangerous.
Term

Met (Metastatic)

Definition
Metastatic refers to cancer that has spread from the primary site to other parts of the body, typically through the bloodstream or lymphatic system.
Term

MMR (Measles, Mumps, and Rubella)

Definition
MMR is a vaccine that protects against three viral infections: measles, mumps, and rubella. These diseases can cause serious health complications, but vaccination can prevent them.
Term

NHL (Non-Hodgkin Lymphoma)

Definition
Non-Hodgkin lymphoma is a group of cancers that originate in the lymphatic system. Unlike Hodgkin lymphoma, NHL does not involve Reed-Sternberg cells and includes various subtypes.
Term

VSZ (Varicella Zoster Virus)

Definition
Varicella zoster virus is the virus responsible for causing chickenpox and shingles. After initial infection, it remains dormant in the body and can reactivate as shingles later in life.
Term

ARDS (Acute Respiratory Distress Syndrome)

Definition
ARDS is a severe lung condition that occurs when fluid builds up in the alveoli, leading to low oxygen levels in the bloodstream. It often results from trauma, infection, or other serious conditions.
Term

BiPAP (Bilevel Positive Airway Pressure)

Definition
BiPAP is a non-invasive ventilator therapy used to help maintain airflow into the lungs by delivering different levels of air pressure during inhalation and exhalation. It is often used to treat sleep apnea and respiratory failure.
Term

BVM (Bag-Valve Mask)

Definition
 A BVM is a handheld device used to provide positive pressure ventilation to patients who are not breathing or are breathing inadequately. It is commonly used in emergency situations.
Term

CF (Cystic Fibrosis)

Definition
Cystic fibrosis is a genetic disorder that affects the lungs and digestive system, causing thick, sticky mucus to build up, leading to respiratory and digestive problems.
Term

COPD (Chronic Obstructive Pulmonary Disease)

Definition
COPD is a chronic lung disease that causes obstructed airflow from the lungs, making it difficult to breathe. It includes conditions such as emphysema and chronic bronchitis.
Term

CPAP (Continuous Positive Airway Pressure)

Definition
CPAP is a treatment that uses mild air pressure to keep the airways open, commonly used in patients with obstructive sleep apnea to prevent airway collapse during sleep.
Term

CXR (Chest X-Ray)

Definition
 A CXR is a diagnostic imaging test that uses X-rays to create pictures of the chest, including the lungs, heart, and bones. It is often used to diagnose conditions like pneumonia or tuberculosis.
Term

FESS (Functional Endoscopic Sinus Surgery)

Definition
FESS is a minimally invasive surgical procedure used to restore normal drainage and function to the sinuses by removing blockages, typically used to treat chronic sinusitis.
Term

HBOT (Hyperbaric Oxygen Therapy)

Definition
HBOT is a treatment that involves breathing pure oxygen in a pressurized room or chamber. It is used to treat conditions such as decompression sickness, serious infections, and wounds that won’t heal.
Term

MDI (Metered-Dose Inhaler)

Definition
An MDI is a device that delivers a specific amount of medication to the lungs in the form of a mist, commonly used to treat conditions like asthma and COPD.
Term

OSA (Obstructive Sleep Apnea)

Definition
OSA is a condition in which the muscles in the throat relax excessively during sleep, causing repeated blockages of the airway and interruptions in breathing.
Term

PNA (Pneumonia)

Definition
Pneumonia is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus, causing symptoms like cough, fever, and difficulty breathing.
Term

PFT (Pulmonary Function Test)

Definition
A PFT is a group of tests that measure how well the lungs are working, including how much air they can hold, how quickly air can be exhaled, and how well the lungs deliver oxygen to the blood.
Term

SIDS (Sudden Infant Death Syndrome)

Definition
