The uploading part is usually where the anxiety kicks in.

You ordered your titers. You got your blood drawn. Your results PDF is sitting in your inbox. And now you're staring at a compliance portal that's demanding "documentation" without telling you exactly what format it wants.

CastleBranch, Complio, ACEMAPP, Verified Credentials, ExactID, and the school-specific portals all work slightly differently. But here's the good news: they all accept titer PDFs. You're not doing anything unusual. Millions of health program students upload titer results every semester through these exact systems.

This page walks through what to expect and how to handle the common snags.

What compliance portals actually check

Portals like CastleBranch and Complio aren't run by your school's admissions office — they're third-party compliance vendors that your school hired to collect and verify medical documents. A real human reviewer looks at each document you upload and either approves it or flags it for correction.

The reviewer is checking for four things:

1. Your name — clearly visible and matching your enrollment record
2. Your date of birth — for identity verification
3. The test name — e.g. "Rubeola IgG" (measles), "Varicella Zoster IgG," "Hepatitis B Surface Antibody Quantitative"
4. The result — with the interpretation ("Immune" / "Positive" / a numeric value above the immunity threshold)

If all four are on the page, the document will almost always be approved. If any are missing or unclear, it gets flagged.

Before you upload — a quick sanity check

Open your results PDF and confirm:

• Your name is spelled correctly and matches how you're enrolled. If your school has you as "Katherine" but the lab has "Kathy," that's a common flag. Contact us and we'll fix the lab's name field so results are reissued correctly.
• Your date of birth is correct. If it's wrong on the report, the whole thing needs to be reissued — don't try to upload it as-is.
• Every test the school asked for is present. Sometimes schools ask for MMR and Varicella but not Hep B; sometimes it's all three plus TB. Cross-reference the compliance list.
• The results are readable — no cut-off text, no scanning artifacts, no watermarks obscuring the numbers.

Uploading to CastleBranch

CastleBranch (myCB) is the most common portal for nursing programs. The upload flow:

1. Log in to your student account at portal.castlebranch.com.
2. Open your compliance tracker. You'll see line items like "MMR Titer," "Varicella Titer," etc., each with a status.
3. Click the specific requirement you want to fulfill. Do not upload a single combined PDF to the general "documents" area — CastleBranch wants each titer attached to its specific requirement.
4. Upload the PDF (or the specific page of the PDF that contains that titer). Accepted formats: PDF, JPG, PNG. Max size is typically 5MB per file.
5. Submit. Review takes 1-3 business days typically. You'll get an email when it's approved or if it's flagged.

If your titer panel PDF has multiple tests on one page: You can upload the same full PDF to each requirement — CastleBranch reviewers are used to this. Or you can use a free tool like Adobe Acrobat online or Preview on Mac to save just the relevant page and upload smaller files. Either works.

Uploading to Complio

Complio (by American DataBank) works similarly to CastleBranch. The interface looks different but the logic is the same: line items for each requirement, upload a PDF per line item, wait for review.

1. Log in at your school's Complio portal (URL is usually school-specific).
2. Open the compliance checklist.
3. For each titer requirement, click "Upload document."
4. Attach the PDF, add a document date if prompted (use the date on the lab report, not the day you're uploading), and submit.

ACEMAPP, Verified Credentials, and the rest

Same principle. Some schools use ACEMAPP for clinical placement tracking. Some use Verified Credentials, ExactID, or in-house portals built into their student information systems. The workflow is always: find the specific requirement line item, attach a PDF that shows your name, DOB, test name, and result, submit.

Common reasons a titer gets flagged

Based on what we hear from customers after they upload:

• "Missing date of birth" — the reviewer couldn't find your DOB on the page. Our reports include DOB, but if the reviewer is picky, add a cover page with your name and DOB or highlight the field.
• "Test result not clearly stated" — usually happens when the report shows only a numeric value without an interpretation line. Send the report to us and we can annotate or reissue with the interpretation stated in plain text.
• "Result is qualitative, we need quantitative" — some schools require the actual antibody value, not just "positive." Check your order — quantitative panels return numbers, qualitative panels return positive/negative. If your school needs quantitative, we can help you re-order the right panel.
• "Non-immune / equivocal result" — this isn't a formatting problem, it's a real result. If your titer came back showing you're not immune, you'll need a booster shot and a follow-up titer. Talk to your student health office about the next step.

What our customers say about the process

"I received my lab order 20 minutes after submitting my order, I was able to find a lab appointment on the same day just 3 miles from my home. I received results less than 24hrs later." — lindsey heberling

"Fast and affordable! Even though I had insurance for some reason it does not cover the titer testing for school. After making payment I received my lab requisition within ten minutes. I went to the lab and had blood drawn and received my results all within 24 hours." — Monica Blair

"I made an appointment online, for two separate tests (had 2 separate appointment times). Everything was quick, easy, and my results came back exactly when they said they would." — LabCorp draw customer

About cost — the honest conversation

We hear complaints about CastleBranch and Complio pricing all the time. The portal itself costs money (usually paid by you as part of your program fees), and every document upload gets reviewed by a person, which is why turnaround takes days rather than seconds. There's not a lot we can do about that — those portals are the standard your school uses.

What we can do is make the lab side of it affordable and fast so you're not compounding one expense with another. That's the whole reason we exist.

If your titer comes back non-immune

Get a booster from your primary care or a pharmacy. Then order a follow-up titer from us (single-test, cheaper than the full panel) about 4-6 weeks after the booster to confirm the immune response. Upload both documents to the compliance portal — the booster record for the shot itself, and the follow-up titer proving it worked.

Most schools accept this workflow. A few require a specific waiting period between booster and re-titer. Check your program's specific instructions.
