This test measures varicella-zoster virus (VZV) IgG antibodies at Quest and reports the result as a numeric antibody index (a signal-to-cutoff ratio) with the lab's interpretation — an index of 1.00 or higher is positive, meaning immunity from prior chickenpox or vaccination. That number is what nursing, EMT, paramedic, and other allied-health programs mean when a health form says the varicella titer must "show values" or be "quantitative"; a report that only says Reactive gets sent back. Our standard Chickenpox (Varicella) Immunity Test ($32.99, Labcorp) reports Reactive/Non-Reactive with no number, so order this version when your form asks for a value. One caveat that applies to every commercial varicella IgG assay: antibody levels after vaccination run lower than after natural infection, so a vaccinated person can occasionally test below the cutoff despite being protected. Programs almost always accept a varicella booster in that case.
Semi-quantitative varicella-zoster virus (VZV) IgG (CPT 86787) reported as a numeric antibody index with interpretation. Documents immunity from prior infection or vaccination for clinical-program, employment, and prenatal requirements that call for a titer value rather than a qualitative result.
Nursing, EMT/paramedic, medical, dental, PA, and other allied-health students whose program form requires a varicella titer "with values"; healthcare hires whose occupational-health office wants a numeric titer; anyone re-checking immunity after a varicella booster.

Yes, in the sense schools and employers use the word: the report shows a numeric antibody index (Quest reports a signal-to-cutoff ratio; 1.00 or higher is positive) alongside the interpretation, rather than a bare Reactive/Non-Reactive. Strictly speaking it's semi-quantitative — an index, not an IU/mL concentration — which is the standard format labs offer for varicella IgG and the one forms asking for "values" are written around.
Same antibody (VZV IgG), different lab and report format. The $32.99 Chickenpox (Varicella) Immunity Test runs at Labcorp and reports Reactive/Non-Reactive only — fine for most employers and general proof of immunity. This version runs at Quest and adds the numeric index. If your form doesn't mention values, save the money and order the standard test.
Quest's cutoff is an index of 1.00: below 1.00 is negative (antibody not detected), 1.00 or above is positive. Your report prints the value and the reference range next to it, which is what verification offices check. Cutoffs differ between labs and assays, so numbers from different labs aren't directly comparable.
Occasionally, yes. Antibody levels after vaccination run lower than after natural chickenpox, and Quest notes this assay may not be sensitive enough to detect vaccine-induced antibodies in every case. A negative result in a vaccinated person doesn't prove you're susceptible, but institutions go by the number — the usual remedy is a varicella booster rather than more testing.
$56.99 on TestWell, drawn at Quest. Quest Health sells the same test (4439) directly for $65 plus a $6 physician fee, and hospital labs commonly bill $150 or more. When a numeric value isn't required, the $32.99 standard immunity test is the cheaper option.
No. No fasting or preparation — it's a standard blood draw at any Quest patient service center. Results post in 1–3 business days as a lab report showing the index value, the reference range, and the interpretation.
Typically an MMR Immunity Test (measles, mumps, rubella IgG), a Hepatitis B Immunity Test (quantitative anti-HBs), and a QuantiFERON TB blood test. MMR and TB can be drawn at Quest in the same visit as this titer; the hepatitis B immunity test currently runs at Labcorp, so it's a separate stop.
