About this test

This test checks for both IgG and IgM antibodies to cytomegalovirus (CMV), a common virus that most people are exposed to at some point. Blue Horizon's own description focuses on why CMV status matters in pregnancy: symptomatic congenital infections are more likely in babies born to mothers who weren't already immune before catching CMV for the first time during pregnancy.

There's no named comparison group for this test, so we can't say how it stacks up against similarly priced immunity tests directly. Against the wider set of immunity and infection tests we track, its £90.25 price sits well below the £124.63 median, and its two-marker combination of IgG and IgM places it in the upper quarter of similarly focused tests by depth, both of which support its scores.

Collection requires a venous blood draw at a clinic, though a nurse home visit is offered, and results take 5 days, which is why its collection convenience score is only middling. A doctor reviews the result. Trust signals reflect Blue Horizon's 4.2 Trustpilot rating from 395 reviews and its UKAS ISO 15189 partner labs, both provider-wide facts rather than specific to this test.

Who is it for?

This suits people who want to check their CMV antibody status, for example women who are pregnant or planning pregnancy and want to understand whether they've already been exposed to CMV, or anyone advised to check their CMV status for another reason. IgG indicates past exposure, while IgM can indicate a more recent infection.

Because there's no comparison group listed, we can't point you to a cheaper or more comprehensive named alternative from our data. If you have symptoms or are pregnant and concerned about CMV, talk to your GP or midwife, since results are best interpreted alongside your wider clinical picture.

How it works

A phlebotomist takes a venous blood sample at a clinic or during a nurse home visit; there's no at-home kit for this test. The lab tests the sample for CMV IgG and IgM antibodies, with results typically back within 5 days. A doctor reviews the results before you receive your report.

Pros & cons

Pros

  • Priced around 28% below the median for similarly sized immunity tests we track.
  • Tests both IgG and IgM, giving a picture of past exposure and more recent infection.
  • A doctor reviews your results before you receive them.
  • A nurse can come to you if a clinic visit isn't convenient.

Cons

  • Collection is clinic- or nurse-visit only; there's no at-home kit for this test.
  • Takes 5 days for results, slower than some of Blue Horizon's other single- or two-marker tests.
  • No named comparison group, so we can't confirm it beats specific rival CMV tests on price or depth.
