Genetic testing
Specialist chromosome tests, with consultant-led counselling.
Parental karyotypeThe number and structure of a parent’s chromosomes£495 per sample
A full karyotype, examining the number and structure of a parent’s chromosomes.
It can help explain recurrent miscarriage or a chromosomal finding in a pregnancy, by looking for a balanced rearrangement of a parent’s chromosomes. This is carried by around 2 to 5 in 100 couples with recurrent miscarriage and usually causes no health problems for the parent.
Chromosomal microarrayFinds small missing or extra genetic material£895 per sample
A high-resolution chromosome test that detects small gains and losses of genetic material that a standard karyotype can miss.
Your consultant will discuss whether testing is right for you and explain your results, including what they may mean for a future pregnancy.
Urine tests
A core part of antenatal care, at key stages or when needed.
Urine dipstickProtein, glucose, ketones and signs of infection£60
Screening for protein, glucose, ketones and signs of infection, to help detect urine infection, high blood pressure in pregnancy and glucose in the urine.
Urinary tract infections are common in pregnancy. Alongside discomfort, they are linked with infection reaching the cervix and womb, which may contribute to waters breaking early and preterm birth.
Mid-stream urine (MSU)Laboratory culture for urine infection£110
Laboratory microscopy, culture and sensitivity, to detect infection with or without symptoms and guide the right antibiotic if needed.
Even infection without symptoms, known as asymptomatic bacteriuria, can be linked with these complications. This is why national guidance recommends a mid-stream urine test early in pregnancy, and treating it lowers the chance of a kidney infection.
Vaginal swabs
Early detection and treatment of infection.
Vaginal swab screeningOne price covers all the tests below£110
Your swab is tested for bacterial vaginosis, group B streptococcus and any symptom-related infection, as needed, for a single price.
Bacterial vaginosis (BV)An imbalance of the normal vaginal bacteria
Assessment for an imbalance of vaginal bacteria, which may be linked with a higher chance of preterm birth in some situations.
BV is common, often causes no symptoms and is easily treated.
Group B streptococcus (GBS)Whether you carry GBS, to plan for birth
Targeted screening to inform your care and birth plan, particularly after a previous GBS-related pregnancy or newborn complication.
GBS is carried by around 2 to 4 in 10 women and is usually harmless, but rarely it can cause serious infection in a newborn baby. It is not routinely tested for on the NHS, so knowing your status means antibiotics can be offered in labour if needed.
Symptom-directed swabFor discharge, irritation or discomfort
Investigation of abnormal discharge, irritation or discomfort, for accurate diagnosis and treatment. Repeat swabs can confirm an infection has cleared.
Untreated infections in pregnancy may be linked with infection reaching the womb, waters breaking early, preterm birth and infection in the newborn.
