Who is this test suitable for? Anyone following the end or a loss of a pregnancy, especially important if you are slow to recover to pre-pregnancy health levels, there has been significant blood loss or had an infection. 

Menopause Check

The menopause is the term given when a woman stops having periods and is no longer able to get pregnant naturally. Periods usually start to become less frequent over a few months or years before they stop altogether. Sometimes they can stop suddenly.


The menopause is a natural part of ageing that usually occurs between 45 and 55 years of age, as a woman's oestrogen levels decline. In the UK, the average age for a woman to reach the menopause is 51. Around 1 in 100 women experience the menopause before 40 years of age. This is known as premature menopause or premature ovarian insufficiency.

Please take this test between days 2 and 4 of your period. It can be taken at any time if you are not having periods. 

B12 (Active) / Red Cell Folate

This test is suitable for anyone who believes they are experiencing symptoms of vitamin B12 deficiency, especially if you suffer from Crohn’s or Coeliac disease where your immune system has problems with vitamin absorption or eat a poor non-supplemented diet.  Certain medications, including anticonvulsants and proton pump inhibitors (PPI’S), can affect vitamin absorption in your body. These vitamins are vital and perform several important functions in the body, including keeping the nervous system healthy.


Although it's uncommon, vitamin B12 or folate deficiency (with or without anaemia) can lead to complications, particularly if you have been deficient in vitamin B12 or folate for some time. Potential complications can include:

  • problems with the nervous system

  • temporary infertility

  • increased risk of heart conditions/heart failure 

  • pregnancy complications and birth defects

Phospholipid Antibodies

This test is suitable for anyone who suspects they have symptoms of APS or have a history of: 

  • 1 or more confirmed blood clots

  • 1 or more unexplained late miscarriages at or after week 10 of your pregnancy

  • 1 or more premature births at or before week 34 of your pregnancy

  • 3 or more unexplained early miscarriages before week 10 of your pregnancy

  • autoimmune disorders who are trying to conceive 


Your care provider may perform a second blood test to confirm positive results. This is because a single positive test can result from a short-term infection. The second blood test often is done 12 weeks or more after the first one.

How can antiphospholipid syndrome affect pregnancy?

APS has also been linked to pregnancy complications, including:

  • Recurrent blood clots

  • recurrent miscarriage 

  • late miscarriage (a miscarriage that happens after the first 12 weeks of pregnancy)

  • stillbirth

  • premature birth

  • pre-eclampsia

  • placental complications

  • fetal growth restriction


Do remember that APS is treatable and with the right treatment and care, most women with APS have successful pregnancies. APS is also one of the most treatable causes of recurrent miscarriage.

When can the test be taken?

At any time before or during pregnancy - Diagnosing APS can sometimes be tricky but can affect people of all ages, including children and babies.


Most people are diagnosed with APS between 20 and 50 years of age, and it affects 3 to 5 times as many women as men.


It's not clear how many people in the UK have the condition.

Anti Müllerian Hormone (2nd Gen)

What is AMH?

Anti-mullerian hormone (AMH) is produced in the ovarian follicles (small fluid-filled sacs where eggs develop). Since AMH is only produced by ovarian follicles, blood levels of this hormone have been used to estimate the number of remaining viable eggs (ovarian reserve) in women. 


An AMH test indicates whether a woman's AMH level is normal for her age and indicates whether there's the expected number of viable eggs. It cannot measure the actual number of viable eggs, nor can it give a precise estimate for the years left that a woman can wait for pregnancy to occur. 


AMH levels decline as you get older and reach menopause, as the quality and number of ovarian follicles decline with age. Women with polycystic ovaries can have higher than expected results for their age. This is because AMH is produced in the ovarian follicles and women with polycystic ovaries often have high numbers of follicles in the early stages of development. 

Who is this test suitable for? 


This test is suitable for:

  • Anyone considering starting a family

  • Anyone struggling to conceive a pregnancy naturally

  • Anyone who has been referred to us for a test

  • Anyone curious about her future fertility 

  • If you wish to check your ovarian reserve is appropriate for your age

  • If you are considering assisted conception 

  • You want to use AMH to investigate for menopause

Blood Grouping

There are 4 blood types (A, B, AB or O) this blood test allows you to find out which type you are. It is useful to know your blood group in case you need to be given blood, for example if you have heavy bleeding (haemorrhage) during pregnancy or birth.

In order to perform this test, you must inform us


  • if you have a history of a blood transfusion  

  • a history of known antibodies

  • received a blood transfusion in the last 3 months


Please note: these testing profiles must not replace any routine or urgent NHS check-up or blood test, anyone who is unable to get an NHS appointment must escalate this through their own GP surgery. 

When to get tested?

Pregnancy and Postnatal blood profiles can be offered at any stage of pregnancy or post-natal recovery period. 

They provide peace of mind and address some of the symptoms relating to crucial chemical and vitamin imbalances, which are often the cause of debilitating conditions such as thyroid disease or iron deficiency anaemia. The symptoms can often make you feel abnormally tired and unable to cope with day-to-day life, this is often felt more during pregnancy and with the inevitable loss of blood that occurs following the birth of a baby, it can also have a significant impact on mental health.


All women should be offered screening for iron deficiency anaemia at their NHS booking appointment as well as at 28 weeks pregnant. However, symptoms can occur before and remain persistent after this point and can often be related to other causes. Unfortunately, you are not routinely followed up or screened after the birth of a baby or sadly, following a miscarriage.

 

Fertility Hormone Testing

Understanding Your Blood Test Results

Hormonal evaluation studies identify hormonal imbalances that may impair your fertility as hormones control every step in achieving pregnancy, from stimulating the development of an egg to ovulation and implantation of a fertilized egg in the uterus. 


Each hormone that plays a role in conception must be produced in a specific amount at a precise time in your menstrual cycle. 


Hormonal studies measure the levels of certain hormones produced by your body during your cycle.


You are likely to have a series of simple blood tests at various points in your cycle. The tests you choose may help your care provider to determine your diagnosis, as well as to identify the best treatment options for your personal circumstances.
