At TestWell it costs $56.99 plus a $6 lab fee, needs no fasting, and results post in 1–3 business days. Physician-authorized with no doctor's visit or insurance needed; draw at Quest. ## Key facts | Fact | Value | | --- | --- | | Price | $56.99 + $6 lab processing fee per order ($62.99 all-in for this test alone) | | CPT code | 86787 | | Sample | Blood draw | | Fasting | Not required | | Results | 1–3 business days | | Labs | Quest Diagnostics | | Biomarkers measured | 1 | | Physician authorization | Included — no doctor's visit, referral or insurance needed | | Payment | Card, HSA or FSA; cash-pay only (no insurance billing) | ## What does the Varicella (Chickenpox) Titer — Quantitative test tell you? Varicella-zoster IgG titer that reports a numeric antibody value, not just positive/negative — for nursing, EMT, and healthcare programs whose forms require a titer "with values." 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. **Clinical use:** 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. ## Who should order it? 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. ## Biomarkers measured - Varicella-Zoster IgG ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $56.99 | $62.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | Rhode Island is not served. Prices are identical online and in the lab; no draw fee or physician fee is added. ## How much does a Varicella (Chickenpox) Titer — Quantitative test cost? A Varicella (Chickenpox) Titer — Quantitative test costs $56.99 at TestWell — $62.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Ordered directly from the labs' own consumer sites, the same test lists at $65.00 at Quest Health and $69.00 at Labcorp OnDemand (list prices checked Sep 12, 2026). Hospital outpatient labs typically bill around $150.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible. | Where you order | Price | One test, all-in | Notes | | --- | --- | --- | --- | | TestWell (drawn at Quest or Labcorp) | $56.99 | $62.99 | Includes the one $6 lab processing fee, charged once per order | | Quest Health (Quest Diagnostics' own site) | $65.00 | $65.00 | [list price checked 2026-09-12](https://www.questhealth.com/product/chickenpox-antibody-test/4439M.html) | | Labcorp OnDemand (Labcorp's own site) | $69.00 | $69.00 | [list price checked 2026-09-12](https://www.ondemand.labcorp.com/lab-tests/chickenpox-immunity-test) | | Hospital outpatient lab, self-pay (typical) | $150.00 | $150.00 | Reference figure; hospital charges vary widely by facility and are often higher | Lab test codes: Quest test code 4439. ## How do you prepare? No fasting required. Bring your program's health form (or a photo of it) so you can confirm it asks for varicella IgG with a numeric value — that is exactly what this report provides. ## Related conditions - Immunity verification (Z11.59) - Vaccine response monitoring (Z23) ## Common questions about the Varicella (Chickenpox) Titer — Quantitative test ### Is this a quantitative varicella titer? 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. ### How is this different from the Chickenpox (Varicella) Immunity Test? Same antibody (VZV IgG), different lab and report format. The $32.99 [Chickenpox (Varicella) Immunity Test](https://www.test-well.com/tests/chickenpox-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. ### What value means I'm immune to chickenpox? 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. ### I was vaccinated as a child — can a varicella titer come back negative? 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. ### How much does a quantitative varicella titer cost without insurance? $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](https://www.test-well.com/tests/chickenpox-immunity-test) is the cheaper option. ### Do I need to fast before this test? 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. ### What other tests do programs usually require alongside it? Typically an [MMR Immunity Test](https://www.test-well.com/tests/mmr-immunity-test) (measles, mumps, rubella IgG), a [Hepatitis B Immunity Test](https://www.test-well.com/tests/hepatitis-b-immunity) (quantitative anti-HBs), and a [QuantiFERON TB blood test](https://www.test-well.com/tests/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. ## How to order 1.
