Past infection of chickenpox refers to previous exposure to the varicella-zoster virus (VZV) that has resolved but left lasting antibodies in the body. It is caused by the varicella-zoster virus, which remains dormant in nerve tissues after the initial infection clears. The Varicella-Zoster Virus (VZV) Antibodies, IgG test is the most important test for confirming past chickenpox infection and immunity status.
Past infection of chickenpox is caused by the varicella-zoster virus (VZV), a highly contagious herpes virus that spreads through respiratory droplets or direct contact with the characteristic itchy blisters. Once you contract chickenpox, your immune system produces antibodies that fight off the active infection, typically within 1-2 weeks. After the infection clears, the virus remains dormant in your nerve root ganglia for life, and your body maintains IgG antibodies that provide lasting immunity against future chickenpox infections.
The Varicella-Zoster Virus (VZV) Antibodies, IgG test is the most important test for confirming past chickenpox infection because it specifically detects IgG antibodies that remain in your bloodstream for life after exposure to the virus. This blood test measures the concentration of these protective antibodies, with high levels indicating immunity from either natural infection or vaccination. The test is essential for healthcare workers, pregnant women, and anyone who needs documented proof of immunity, especially when childhood infection history is unclear or unavailable.
You should get tested if you are unsure whether you had chickenpox as a child and need to verify immunity for employment in healthcare settings, during pregnancy planning, before starting immunosuppressive medications, or if you have been exposed to someone with active chickenpox. Testing is also important if you are over age 50 and considering the shingles vaccine, as past chickenpox infection is required for shingles to develop. Many schools, hospitals, and medical programs require documented proof of immunity through blood testing rather than relying on personal or parental recollection.
What this means
Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
Recommended actions
Increase resistance or strength training
Prioritize 7–8 hours of quality sleep per night, try to reduce stress
Include more zinc- and magnesium-rich foods (like shellfish, beef, pumpkin seeds, spinach)
Consider retesting in 3–6 months
