Laboratory Department Categorization for Diagnostic Tests Quiz

Hematology is the branch of medicine concerned with the study of blood, blood-forming organs, and blood diseases.

Type O blood is considered the universal donor as it lacks A and B antigens, reducing the risk of incompatible transfusions.

Thyroid function tests assess the production of thyroid hormones, including T3, T4, and thyroid-stimulating hormone (TSH), to diagnose thyroid disorders.

DEXA scan measures bone density and assesses the risk of fractures and osteoporosis.

Troponin test measures the levels of cardiac troponin proteins released into the blood when the heart muscle is damaged, aiding in the diagnosis of heart attacks and other cardiac conditions.

PCR is a laboratory technique used to make multiple copies of a segment of DNA.

Renal Function Test evaluates the kidneys' ability to filter and eliminate waste products from the blood.

A differential white blood cell count is performed to quantify and categorize the different types of white blood cells present in a blood sample.

HbA1c test measures the average blood sugar level over the past two to three months, indicating long-term glucose control and diagnosing diabetes.

The urea breath test detects the presence of Helicobacter pylori bacteria in the stomach by measuring the amount of carbon dioxide produced when urea is broken down.

CBC is a blood test used to evaluate overall health and detect a wide range of disorders by measuring the cellular components of blood, including red and white blood cells and platelets.

PT test measures the time it takes for blood to clot, evaluating the extrinsic pathway of coagulation and monitoring anticoagulant therapy.

An ANA test detects antinuclear antibodies, which are often present in systemic lupus erythematosus (SLE) and other autoimmune diseases.

hCG, or human chorionic gonadotropin, is measured in pregnancy tests to confirm pregnancy as its levels rise significantly during early pregnancy.

ELISA is a laboratory technique used to detect and measure antibodies, antigens, proteins, and hormones in biological samples.

Serology primarily focuses on detecting antibodies, antigens, or other substances in blood serum related to immune responses.

MRI, or Magnetic Resonance Imaging, produces detailed images of internal body structures using a strong magnetic field and radio waves.

A sputum culture and sensitivity test is used to detect and identify bacteria or fungi causing respiratory infections and determine the most effective antibiotic or antifungal treatment.

A hepatitis panel test detects antibodies or antigens associated with different types of hepatitis, including Hepatitis B virus.

ALT is an enzyme found in the liver. Elevated levels in the blood may indicate liver damage or disease.

Type A blood contains A antigens on its red blood cells, and it has antibodies against type B blood.

LDL cholesterol, or low-density lipoprotein cholesterol, is often referred to as 'bad' cholesterol because it contributes to plaque buildup in the arteries, increasing the risk of heart disease.

Nucleic acid tests (NATs) are used to detect the presence of viral RNA or DNA, commonly used for diagnosing infections such as Hepatitis C virus (HCV) and HIV.

FEV1 measures the amount of air forcefully exhaled in one second during a pulmonary function test, providing information about lung function and diagnosing respiratory conditions.

PSA is a protein produced by the prostate gland. Elevated PSA levels in the blood may indicate prostate cancer or other prostate conditions.
