Varicella Titers Test (Varicella-Zoster Virus Antibody Test):

• Who should get this test: Patients with uncertain or unknown history of chickenpox (varicella) or varicella vaccination, individuals at risk of varicella exposure such as healthcare workers, pregnant women, or those planning pregnancy, or those undergoing evaluation for immunity to varicella.

• What's included in the test: The Varicella Titers test measures levels of antibodies against the varicella-zoster virus (VZV) in the blood. It involves collecting blood samples and testing for the presence of specific antibodies (IgG) against the virus.

• Why someone would check this test: To determine immunity to varicella, confirm prior varicella infection or vaccination, guide vaccination recommendations or treatment decisions in high-risk individuals, assess susceptibility to varicella during pregnancy, or fulfill requirements for school, work, or travel.

Hepatitis B Titers (HBV Titers):

• Who Should Get This: Patients who have received the hepatitis B vaccine, individuals at risk of hepatitis B infection due to occupational exposure (healthcare workers, laboratory personnel), those planning to travel to regions with high hepatitis B prevalence, or individuals with liver disease or immunocompromised conditions may undergo this test.

• What's included in the test: The test measures the level of antibodies (anti-HBs) produced by the body in response to hepatitis B virus (HBV) vaccination or previous HBV infection. It can be done using a blood sample obtained from a vein in the arm.

• Why someone would check this test: Hepatitis B titers help in assessing immunity to HBV and determining the need for booster vaccinations. Adequate antibody levels indicate protection against HBV infection, while low or undetectable titers may indicate the need for additional vaccine doses or evaluation for possible HBV infection. Healthcare providers use this test to ensure immunity in individuals at risk and to guide vaccination strategies for optimal protection against hepatitis B.

Measles Titers Test (Measles Antibody Test):

• Who should get this test: Patients with uncertain or unknown history of measles infection or measles vaccination, individuals at risk of measles exposure such as healthcare workers, travelers to areas with measles outbreaks, pregnant women, or those planning pregnancy, or those undergoing evaluation for immunity to measles.

• What's included in the test: The Measles Titers test measures levels of antibodies against the measles virus in the blood. It involves collecting blood samples and testing for the presence of specific antibodies (IgG) against the virus.

• Why someone would check this test: To determine immunity to measles, confirm prior measles infection or vaccination, guide vaccination recommendations or treatment decisions in high-risk individuals, assess susceptibility to measles during pregnancy or in healthcare settings, or fulfill requirements for school, work, or travel in areas with measles outbreaks.

Mumps Titers Test (Mumps Antibody Test):

• Who should get this test: Patients with uncertain or unknown history of mumps infection or mumps vaccination, individuals at risk of mumps exposure such as healthcare workers, travelers to areas with mumps outbreaks, pregnant women, or those planning pregnancy, or those undergoing evaluation for immunity to mumps.

• What's included in the test: The Mumps Titers test measures levels of antibodies against the mumps virus in the blood. It involves collecting blood samples and testing for the presence of specific antibodies (IgG) against the virus.

• Why someone would check this test: To determine immunity to mumps, confirm prior mumps infection or vaccination, guide vaccination recommendations or treatment decisions in high-risk individuals, assess susceptibility to mumps during pregnancy or in healthcare settings, or fulfill requirements for school, work, or travel in areas with mumps outbreaks.

Rubella Titers Test (Rubella Antibody Test):

• Who should get this test: Patients with uncertain or unknown history of rubella infection or rubella vaccination, pregnant women, or those planning pregnancy, individuals at risk of rubella exposure such as healthcare workers, travelers to areas with rubella outbreaks, or those undergoing evaluation for immunity to rubella.

• What's included in the test: The Rubella Titers test measures levels of antibodies against the rubella virus in the blood. It involves collecting blood samples and testing for the presence of specific antibodies (IgG) against the virus.

• Why someone would check this test: To determine immunity to rubella, confirm prior rubella infection or vaccination, guide vaccination recommendations or treatment decisions in high-risk individuals, assess susceptibility to rubella during pregnancy or in healthcare settings, or fulfill requirements for school, work, or travel in areas with rubella outbreaks.

Quantiferon Gold Test (QFT-G):

• Who should get this test: Patients suspected of tuberculosis (TB) infection, individuals with known TB exposure, healthcare workers, those with compromised immune systems, or those undergoing evaluation for TB infection or latent TB.

• What's included in the test: The Quantiferon Gold test measures the body's immune response to TB bacteria by detecting interferon-gamma release from T cells exposed to TB antigens. It involves collecting blood samples and incubating them with TB-specific antigens, then measuring interferon-gamma levels.

• Why someone would check this test: To diagnose latent TB infection (LTBI) in individuals at risk of developing active TB, especially in populations where TB prevalence is high, to guide treatment decisions for LTBI, or to screen for TB infection in healthcare settings, prisons, or immigration centers.
