This page explains how to prepare for a Tetanus & Diphtheria IgG Immunity Test in Highland Acres, DE, what the test measures, and what to confirm with the collection lab. This blood test checks whether you have protective IgG antibodies against tetanus and diphtheria, which generally reflects past vaccination or prior exposure.
What the Tetanus & Diphtheria IgG Immunity Test measures
The test measures levels of IgG antibodies directed against tetanus and against diphtheria in your bloodstream. These antibody levels are used as an indicator of whether you still have protection from prior vaccination. Some labs report a combined immunity interpretation for each component separately.

How to prepare for the Tetanus & Diphtheria IgG Immunity Test
Expect little to no preparation for this test. Confirm any timing or fasting details with the collection site when you schedule your appointment.
- Confirm with the collection site whether any fasting or timing instructions apply to your appointment.
- Stay well hydrated before your visit, since hydration can make a blood draw easier.
- Wear a short-sleeved or loose-sleeved top so the arm is easy to access.
- Bring your photo ID, insurance card if applicable, and your test order or requisition.
- Tell the collector about any blood-thinning medication, recent vaccinations, or prior antibody testing, as these may be relevant to interpretation.
- Arrive a few minutes early so you can check in and settle before the draw.
Fasting, timing, sample type, and what to bring
Fasting
Fasting is generally not required for this antibody test, but some facilities may combine it with other tests that do require fasting. Follow the instructions on your order and confirm with your lab.
Best time to collect
This test can usually be collected at any time of day, since it is not tied to a specific daily rhythm. If your clinician wants to assess immunity after a recent vaccination, they may recommend waiting a set interval, so confirm the preferred timing with your lab.
Sample type
Blood draw. The collector will explain the process before starting.
What to bring
- Your printed lab order or requisition form — the ordering physician prepares it for you after you order, and you print it (or fax it from your account) before visiting
- Your order confirmation email, in case the collection site asks to see it
- A short-sleeved or loose-sleeved shirt for an easy blood draw
- Water to drink before the draw and a light snack for afterward, if your test requires fasting
- A government-issued photo ID (most collection sites verify identity at check-in)
- A written list of the medications and supplements you currently take
You do not need an insurance card or a payment method at the collection site: the lab does not bill insurance, and you pay at order time, so there is no copay or deductible. The lab also provides the physician's requisition, so you do not need a separate doctor's referral.
Order process and what-to-bring details reflect the lab's published instructions, paraphrased in our own words. Confirm final requirements with the collection lab that will perform your draw.
What the collection involves
A trained collector draws a small sample of blood, usually from a vein in your arm, using a needle and collection tube. The sample is then sent to a laboratory for antibody analysis, and the draw itself typically takes only a few minutes.
Details worth confirming with the collection lab before your visit:
- Does this test require any fasting or timing restrictions?
- When and how will I receive my results?
- Should I wait a certain interval after a recent vaccination before testing?
Why a clinician may order this test
A clinician may order this test to check whether your tetanus and diphtheria immunity is still adequate, especially before travel, after an injury, or when vaccination history is unclear. It can also help guide decisions about whether a booster is appropriate.
Understanding your results
Reference ranges and immunity thresholds vary by laboratory, so your report will list the range used by the lab that performed the test. Your clinician interprets the numbers alongside your vaccination history and overall health, so discuss the findings with them rather than comparing across labs.
Preparing in Highland Acres
If you are preparing in Highland Acres, plan around the lab's hours rather than the other way around, especially when a fasting window is involved.
General test information is compiled from publicly available reference material, including MedlinePlus (medlineplus.gov) and the Centers for Disease Control and Prevention (cdc.gov), and is reviewed for clarity. Preparation and what-to-bring details reflect the lab's published instructions, paraphrased into our own words. Preparation instructions, timing, and pricing vary by collection lab — always confirm them with the lab that will perform your draw.
Common questions
Frequently asked questions
Do I need to fast for this test?
Fasting is usually not necessary for a tetanus and diphtheria antibody test. If your order includes other tests that require fasting, follow those instructions and confirm the details with your lab.
How long does it take to get results?
Turnaround is typically one to three business days, though this can vary by laboratory and how the sample is transported. Ask your collection site when to expect your report.
Can this test tell me if I need a booster?
It measures antibody levels that reflect your immunity status, which your clinician can review alongside your vaccination history. Whether a booster is appropriate is a decision your clinician makes based on those results.
Does a recent vaccination affect the test?
A recent tetanus or diphtheria vaccination can influence antibody levels, so tell your clinician and the collection site about any recent shots. They may advise waiting a certain interval before testing.
