Group B Streptococcus Screening For Pregnant Women 'Not Recommended' By National Screening Committee

'Much better evidence is needed on such widespread antibiotic use.'

Screening pregnant women for Group B streptococcus (GBS) is “not recommended” by the National Screening Committee (NSC).

About 150,000 pregnant women carry GBS each year in the UK and, in some cases, will pass the bacteria to their baby in labour.

In January 2016, a couple appealed for the pregnancy screening to be made mandatory, after their baby died from an infection that could have been prevented if caught early by a simple test.

However at the time, the NSC said the test should not be offered to all pregnant women as there was “insufficient evidence” to demonstrate that the benefits would outweigh the harms.

Now, following a further comprehensive review of the evidence, the independent screening committee has stood by the decision to not recommended a national screening programme for GBS in pregnancy.

Dr Anne Mackie, director of programmes for the UK NSC, said: “At the moment there is no test that can distinguish between women whose babies would be affected by GBS at birth and those who would not.

“This means that screening for GBS in pregnancy would lead to thousands of women receiving antibiotics in labour when there is no benefit for them or their babies and the harms this may cause are unknown.

“This approach also cuts against the grain of ongoing efforts to reduce the number of people receiving unnecessary antibiotics.

“Much better evidence is needed on such widespread antibiotic use among pregnant women and whether it is possible to find a more accurate test.”

Each year in the UK, there are between 400 to 500 cases of early onset GBS, which occurs in the first seven days of a baby’s life. With prompt treatment, the vast majority of babies affected by this condition will fully recover, Public Health England stated. 

It has been suggested that offering screening at a later stage (35 to 37 weeks of pregnancy) will help detect women carrying GBS who are more at risk of passing on the bacteria during labour.

However, the Committee still found that even screening at this later stage would cause more harm than good, with large numbers of people still unnecessarily receiving antibiotics.

As part of a regular review process, these recommendations will be looked at again in three years – or earlier if significant new evidence becomes available.

The latest screening recommendations were made at the UK NSC’s meeting on 8 February 2017, the minutes of which were published on 22 March, 2017. 

In January 2016, Shaheen McQuade, 24, and Craig Blackie, 32, gathered 12,000 signatures on a petition calling for all pregnant women to be given the swab test that detects the Group B infection.

The couple’s son Zach Blackie died in August 2015, when he was just two weeks old, after contracting the early-onset GBS (group B streptococcus) infection, which lead to meningitis. McQuade unknowingly carried the infection.

The couple presented the petition to Holyrood’s public petitions committee and MSPs promised to take “definitive action” on the matter.

“No mother should ever have to cope with losing a baby,” McQuade told HuffPost UK Parents at the time. 

“To live with the knowledge that it was preventable is a million times worse. It is indescribable the feeling I have to learn that a simple test would have saved my son’s life.

“The NHS took a gamble with my son’s life and they lost.”

Pregnancy worries and words of comfort
I have no morning sickness! Is that bad news?(01 of10)

You might have read things about how morning sickness signifies a healthy level of pregnancy hormones – but not having morning sickness does not mean you're lacking! Although many women suffer with it (and 'suffer' really is the word), many other women do not. Some women have it one pregnancy, but not in another. Attend all your usual checks and count yourself as one of the lucky ones! (credit:Alamy )
I drank before I knew I was pregnant, I might have harmed the baby(02 of10)

This happens to many, many expectant mums, and it's unlikely to be a cause for concern at all. Mention it to your GP/midwife, and just keep off the booze now, until you can enjoy a celebratory glass of fizz when your bundle arrives. (credit:Alamy )
I'll lose the baby(03 of10)

It's estimated about one in five pregnancies ends in early miscarriage, and it's thought most of those occur simply because the foetus wasn't developing properly. It does happen, but don't let it rule your thoughts because the vast majority of pregnancies do succeed. Try not to worry and remember that once you're into the second trimester, the chances of miscarriage is dramatically reduced. (credit:Alamy )
My baby might not be 'perfect'(04 of10)

It's estimated that one in 16 babies in the UK is born with a birth defect – but this figure refers to all birth defects, and many are mild and can be treated. So it's likely your baby won't have a birth defect, and even if they do, they will be perfect in their own way – remember support is available for every eventuality. Take your folic acid and attend your antenatal screening appointments. (credit:Alamy )

You might have read terrifying stories about pregnant women giving birth in car parks and taxis – but these stories make it to the news because they are extraordinary, in the literal sense of the word! It very rarely happens, and most women get plenty of warning that labour is beginning. So plan well, and all is very likely to be fine. (credit:Alamy )

If you do end up needing a c-section, you might feel disappointed – but believe us, in the moment the only thing you'll really care about is the safe delivery of your baby. It won't be the end of the world and you won't care a jot when your baby is in your arms. (credit:Alamy )
I won't be able to cope during labour(07 of10)

There is just no telling how labour will be for you, so don't worry about it now. Make your birth plan, discuss it with your partner and midwife, and go with the flow on the day (it's okay to change your mind!). There will be lots and lots of help and support at your disposal. Not to mention drugs, should you need them. (credit:Alamy )
Labour will humiliating (will I poo on the bed?!)(08 of10)

You've heard about that then? It can happen, but the doctors and midwives have seen it all – they have experienced every possible scenario. They won't be worrying about things like that, so neither should you. (credit:Alamy )
I don't know how to be a mum(09 of10)

No-one does until they become one! Every new mum feels like they're winging it in the early days. As your baby grows and you get to know them, you'll learn. Trust in the fact that just about every mother has gone through it… and survived. (credit:Alamy )
I'm worried about gaining all that weight(10 of10)

You will put on weight, yes – but it's normal and nothing to be afraid of! Much weight gain is actually down to the baby, the placenta, extra blood in your system and the retention of water. Pregnancy changes your body in myriad ways – just enjoy it, and let your body just do its thing at this special time. Remember, there's no need to 'eat for two'… but eat what you need and don't count calories. (credit:Alamy )
