A Parent's Guide to Titers and Immunity Requirements for Students Entering Health Programs

If you're reading this, you're probably the one making it happen.

Most calls we get from parents start the same way: your kid got into a nursing program, a PA program, a dental hygiene track, a paramedic course, or a summer clinical internship. The acceptance letter was thrilling. Two weeks later, a compliance email arrived with a list of medical records nobody in the house has looked at in a decade.

The list usually asks for proof of immunity to MMR, Hepatitis B, and Varicella. Sometimes a TB test. Sometimes a current Tdap. And a deadline that feels aggressive.

Your kid is stressed. Their pediatrician's office may not exist anymore. You're not sure where the shot records went. The compliance portal — CastleBranch, Complio, ACEMAPP, or something else — is unforgiving about formatting, and the school won't help.

This page is for you. Here's what you actually need to know.

The short version

  • Your child probably does not need to get re-vaccinated. A blood test called a titer proves they still have immunity from the shots they got as a baby and in school. Most schools accept titer results as proof of compliance.
  • A titer is one blood draw. No provider visit, no waiting room. You order online, we email a lab order, they walk into LabCorp or Quest, and results come back in a few business days.
  • It's usually cheaper than re-vaccinating. A full MMR / Hep B / Varicella immunity panel costs less than the sum of the pharmacy copays and provider visits it would take to re-do those vaccines. The Hep B series alone takes six months if you're starting from scratch.

Why we exist

We started offering online lab testing about ten years ago because parents kept running into the same wall: pediatric records that couldn't be found, primary care offices that wouldn't order routine titers without a full physical, and pharmacies that would happily re-vaccinate rather than help sort out the paperwork.

Our clinics had been offering these labs on demand since 2008. Moving the ordering process online was the obvious next step — most of the calls we got were the same conversation, and the same panels solved most of them.

What the compliance list actually means

School compliance emails are written by administrators, not by patients. Here's what the terms translate to in plain English:

"Proof of MMR immunity" — Either (a) documentation of two MMR shots, or (b) a positive MMR titer showing measles, mumps, and rubella antibodies. If you can't find the shot records, the titer is the answer.

"Proof of Hepatitis B immunity" — Either (a) documentation of the full three-shot Hep B series, or (b) a positive Hep B surface antibody titer. Many people got the series as infants and never think about it again. A titer confirms it worked.

"Proof of Varicella (chickenpox) immunity" — Either (a) two chickenpox shots, (b) a positive varicella titer, or (c) some schools accept "a doctor's note stating you had chickenpox as a child." The titer is the cleanest evidence.

"Current Tdap" — This is a shot, not a titer. Most schools want a Tdap booster within the last 10 years. Any pharmacy can give it — CVS, Walgreens, Costco. Your primary care office can too. Just make sure the vaccination record has a clear date on it.

"TB test" — Either a two-step PPD skin test (two visits about a week apart) or a single QuantiFERON / T-Spot blood test. If your child got a BCG vaccine (common in kids born or raised outside the US), get the blood test — skin tests give false positives after BCG.

A word about Tdap

We offer Tdap on our site, but we'll tell you the same thing we tell everyone: getting the Tdap shot at a pharmacy is usually easier and cheaper than getting it through us. We offer it as a one-stop convenience. If your family already uses a pharmacy or primary care office, get the shot there.

There is a Tdap titer test, and we offer that too, but most schools won't accept it as proof of compliance. Unless the program specifically asks for a titer, don't order it. Just get the shot.

What we recommend for most parents

For students entering health programs, the standard panel that covers most compliance lists is:

  • Immunity Panel (MMR, Hep B, Varicella) — the three titers almost every program asks for.
  • A TB test — QuantiFERON blood test in most cases; two-step PPD skin test if the school specifically requires it.
  • Tdap shot from a pharmacy — see note above.

If your child is a minor, you'll want the School Immunity Panel for Minors instead. It's structured to handle parental consent for children under 18 and includes the panels most middle school and dual-enrollment programs ask for.

Send us the school's compliance email if any line item is confusing. We read these constantly and we can usually tell you within a few minutes exactly what to order.

What parents have told us

"I did a MMR titer test through LabReqs and I am fully satisfied with the customer service, fast delivery of results as well as affordable price. For the blood draw they referred me to a lab that was just a mile away from my home. I had the blood draw on a Saturday and the results came on Tuesday morning. I highly recommend them and will definitely use their service in the future for my family." — Vidya P.
"My school recommended them as the cheapest place to get labwork without a doctor." — Pam M.
"I run a staffing company and place medical professionals. I use LabReqs.com all the time." — R P.
"I found this service on the internet and needed it for my daughter to get into a Rad Tech internship. It was perfect. It was also over $600.00 less than the cost of doing the tests individually. Everything was done quickly and efficiently." — Joan Korth

The process, step by step

  1. You order online. Pick the panel. Checkout takes about a minute.
  2. We email a lab order. Usually within an hour of your order. It's a real physician-signed requisition.
  3. Your child walks into LabCorp, Quest, or a partner clinic. No appointment needed at most locations. Tell them it's a titer draw and show the requisition on their phone.
  4. Results come back in 2-5 business days. PDF, delivered by email, password-protected with your child's date of birth.
  5. Upload to the compliance portal. CastleBranch, Complio, and the rest all accept the PDF the same way they'd accept a shot record.

Two things worth knowing

Save the PDF somewhere permanent. Google Drive, Dropbox, a family folder — anywhere your child will still have access in five years. The same records get asked for again at graduate school, hospital credentialing, and job changes. Skip the future headache.

Insurance usually doesn't help here. Most insurance plans don't cover titer testing when it's for school compliance rather than a medical reason. That's why students end up paying pharmacy retail prices for re-vaccination they don't need. Ordering directly and paying cash is often the cheapest path even for insured families.
