“Submit titers or proof of immunity” is one of the most misread lines on any nursing school checklist. Students order blood tests they didn't need, submit the wrong antibody class, or discover in August that an equivocal result means a booster and a repeat draw. Here's how to get it right the first time.
What a titer proves — and when you need one
A titer measures antibody levels to demonstrate immunity. Programs commonly accept a positive IgG titer in place of vaccination records for MMR (measles, mumps, rubella), hepatitis B, and varicella. If you have complete documented vaccination records, you usually don't need a titer at all — most programs accept a documented two-dose MMR series or a completed three-dose hepatitis B series on its own. Titers matter most for students with lost records, incomplete series, or documentation from another country.
The four mistakes that cost students weeks
- IgM instead of IgG. IgG generally reflects lasting immunity; that's what programs want. An IgM result typically won't satisfy the requirement.
- Buying titers you didn't need. If your vaccine records are complete and your program accepts them, a titer is money you didn't have to spend. Read the rule first.
- Ignoring the equivocal result. Equivocal or non-immune means booster, then repeat titer — a multi-week sequence. Discovering it two weeks before clinicals is the problem.
- Uploading page 1 of 3. Lab reports often carry the name, collection date, and result on separate pages. Partial uploads are the single most common rejection reason we see — and why our reviewers tell you exactly which page is missing instead of just flagging it red.
For program directors: encode the rule, don't explain it 200 times
Titer-versus-dose logic is where generic compliance software fails most visibly: a platform that treats “hepatitis B” as one checkbox can't tell a completed three-dose series from a single dose plus an equivocal titer — but a hospital can, and will. Our portal encodes your program's actual rule, and trained staff review every document within 24 hours with specific rejection notes so students fix problems in March instead of discovering them in August. $30 per student, unlimited free admin and faculty accounts, live within 24–48 hours.

Frequently asked questions
What is a titer?
A blood test that measures antibody levels to show whether you're immune to a specific disease. Programs typically accept a positive IgG titer as proof of immunity in place of vaccination records for diseases like measles, mumps, rubella, hepatitis B, and varicella.
Do I need a titer if I already have my vaccine records?
Usually not. Most programs accept complete, documented vaccination series — for example, two documented MMR doses or a completed three-dose hepatitis B series. Titers exist mainly for students whose records are lost, incomplete, or from another country. Check your program's specific rule; requirements vary.
What does an 'equivocal' or 'non-immune' titer mean?
It means the antibody level didn't clearly demonstrate immunity. The usual next step is a booster dose (or a repeat series) followed by a repeat titer. It doesn't mean you did anything wrong — immunity genuinely wanes for some people.
Is an IgM titer the same as an IgG titer?
No, and this is one of the most common rejection reasons we see. IgG generally reflects long-term immunity, which is what programs require. An IgM result usually won't satisfy an immunity requirement, and a student who submits one has to start over.
How long do titer results take?
Typically a few business days after the blood draw, though it varies by lab and test. Build in time for the possibility of an equivocal result requiring a booster and repeat titer — that sequence can take weeks.
Who decides what my program accepts?
Your program, guided by its clinical affiliation agreements. That's why two nursing schools in the same city can have different rules — and why a document accepted at one hospital may be rejected at another.
