About this test

This test checks for Rubella IgM antibodies. Better2Know's own information explains that IgM antibodies are typically the first your immune system produces after rubella infection, appearing as the rash starts to fade, so a positive result together with a positive IgG suggests a recent or active infection rather than long-standing immunity. Better2Know advises that if both come back positive, testing should be repeated in three to four weeks, or sooner if symptoms develop.

Counted as a single biomarker, this test sits around the middle of the range for clinical depth among the immunity tests we track. Its £195 price is above the median for similarly sized immunity tests, which is the main reason it scores below average on value for money. The listing is clear, with a full description, the biomarker tested, a stated one-day turnaround and clear collection options.

The remaining scores reflect collection and follow-up. You can have blood drawn at a clinic or by a home nurse visit, with results ready the next working day. Results are not doctor-reviewed as standard, which is the main reason it loses marks on results and follow-up; Better2Know says a positive result should prompt medical attention, particularly during pregnancy, and that it can arrange a private consultation. Trust signals reflect a 4.2 Trustpilot score from 775 reviews, CQC registration, and 18 years trading.

Who is it for?

This suits you if you have recent rubella-type symptoms, such as a rash, fever or swollen lymph nodes, or a known recent exposure, and want to check for markers of an active infection rather than long-term immunity.

If you mainly need to confirm long-term immunity rather than investigate current symptoms, an IgG-only immunity check would be more relevant; Better2Know has not linked this test to a named group of comparable products, so there is no pricing data here to compare. If you are pregnant and have symptoms, see a GP promptly rather than relying on this test alone.

How it works

You provide a venous blood sample at a Better2Know clinic, or a nurse can visit you to take the sample. The sample is analysed for Rubella IgM antibodies, with results ready within one working day of the sample reaching the lab. You view your results through Better2Know's online patient area, and the patient services team contacts you once they are ready. Results are not doctor-reviewed as standard.

Pros & cons

Pros

  • Next-day results from sample arrival at the lab.
  • Targets antibodies linked to a recent or active infection rather than only past immunity.
  • Home nurse visit available if you would rather not attend a clinic.

Cons

  • £195 sits above the median price for similarly sized immunity tests we track.
  • If your result is positive, Better2Know recommends repeat testing in three to four weeks to confirm.
  • Your results are not reviewed by a doctor as standard.
