Overview of the Genotype Blood Test
The Genotype Blood Test is a comprehensive 20-biomarker blood profile assessing haemoglobin variants, sickle cell status, blood group and key Full Blood Count measurements.
It combines Haemoglobin Electrophoresis with Haemoglobin A2, Haemoglobin F and a Sickle Cell Screen Solubility Test.
These specialist haemoglobin investigations can provide information about inherited haemoglobin patterns and carrier states that may be relevant to conditions such as sickle cell disease, sickle cell trait and some forms of thalassaemia.
The profile also includes Blood Group together with important red-cell, white-cell and platelet measurements.
This makes the Genotype Blood Test broader than a stand-alone haemoglobin electrophoresis test.
It may be particularly useful before pregnancy, where there is a family history of haemoglobin disorders, following an abnormal blood count or where a fertility, maternity or haematology service has requested more detailed testing.
The Genotype Blood Test costs £160.
Professional sample collection is available in clinic for an additional £35 or through an at-home phlebotomy visit for an additional £60.
What Does the Genotype Blood Test Check?
The Genotype Blood Test measures 20 biomarkers covering haemoglobin variants, sickle cell screening, blood group, red blood cells, white blood cells and Platelets.
Haemoglobin A2 - Measures the proportion of Haemoglobin A2, which can provide useful information during investigation of inherited haemoglobin conditions including some thalassaemia patterns.
Haemoglobin - Measures the oxygen-carrying protein within red blood cells and is an important marker when assessing anaemia and blood health.
Haemoglobin Electrophoresis - Separates different haemoglobin types within the blood to help identify normal and variant haemoglobin patterns.
Haemoglobin F - Measures foetal Haemoglobin, which is normally present at low concentrations in adults but may be increased in certain inherited haemoglobin conditions.
Sickle Cell Screen Solubility Test - Screens for the presence of Haemoglobin S associated with sickle cell trait or sickle cell disease.
Blood Group - Determines the patient's blood group according to the laboratory blood-grouping system.
Red Blood Count - Measures the number of circulating red blood cells.
HCT - Measures Haematocrit, the proportion of blood volume made up of red blood cells.
MCV - Measures Mean Cell Volume, the average size of red blood cells.
MCH - Measures Mean Cell Haemoglobin, the average amount of Haemoglobin contained within each red blood cell.
MCHC - Measures Mean Cell Haemoglobin Concentration, the average concentration of Haemoglobin within red blood cells.
RDW - Measures Red Cell Distribution Width, showing variation in red blood cell size.
White cell count - Measures the total number of circulating white blood cells.
Neutrophils - Measures a major white-cell population involved particularly in bacterial infection and inflammatory responses.
Lymphocytes - Measures white blood cells involved in adaptive immune responses.
Monocytes - Measures immune cells involved in inflammation and clearance of damaged cells and microorganisms.
Eosinophils - Measures white cells associated particularly with allergic and parasitic responses.
Basophils - Measures a smaller white-cell population involved in inflammatory and allergic responses.
Platelets - Measures cells involved in normal blood clotting.
MPV - Measures Mean Platelet Volume, providing information about the average size of circulating Platelets.
Who May Benefit From the Genotype Blood Test ?
The Genotype Blood Test may be useful for people who want a broader assessment of inherited haemoglobin patterns together with Full Blood Count information and blood grouping.
People planning a pregnancy - Knowing haemoglobin carrier status can be important when assessing inherited risk for future children.
People whose partner carries a haemoglobin variant - Testing can help establish whether both reproductive partners carry a clinically relevant inherited haemoglobin trait.
People with a family history of sickle cell disease or sickle cell trait - Haemoglobin Electrophoresis and Sickle Cell Screening can provide important information.
People with a family history of thalassaemia - Haemoglobin A2, Haemoglobin F and red-cell indices can provide useful laboratory information.
People with an abnormal Full Blood Count - Red-cell indices may help provide additional context when inherited haemoglobin disorders are being considered.
People who want to know their blood group - Blood Group testing is included within the profile.
People undergoing fertility or maternity assessment - Haemoglobin genotype information may be requested before or during pregnancy.
People advised by a haematology specialist to undergo haemoglobin testing - The profile combines specialist haemoglobin investigations with key blood-cell markers.
Symptoms and Reasons to Consider the Genotype Blood Test
Many people carrying a haemoglobin variant may have no symptoms, so testing is often performed because of family history, reproductive planning or previous laboratory results.
A known family history of sickle cell disease - Testing can help identify Haemoglobin S and relevant haemoglobin patterns.
A known family history of thalassaemia - Haemoglobin A2, Haemoglobin F and red-cell indices may contribute to investigation.
A reproductive partner has sickle cell trait or another haemoglobin variant - Testing both partners can help assess inherited risk.
Unexplained anaemia - Haemoglobin and red-cell measurements may provide useful information.
Low MCV or small red blood cells on a previous blood test - Further haemoglobin investigation may be appropriate.
Previous abnormal antenatal or haemoglobin screening - More detailed testing may be recommended.
Preconception or fertility planning - Carrier information can be useful before pregnancy.
Need to confirm blood group alongside genotype testing - Blood Group is included within this profile.
People with haemoglobin carrier states may be completely well and may only discover their status through screening.
Significant anaemia, recurrent severe pain episodes or another suspected haemoglobin disorder should receive appropriate clinical or haematology assessment.
How to Prepare
Recent blood transfusion is particularly important to disclose because donor red blood cells can temporarily alter the haemoglobin pattern detected.
If an unusual result requires further clarification, additional genetic or haematology testing may sometimes be recommended.
How to Book Your Genotype Blood Test
The Genotype Blood Test can be booked privately with professional venous blood collection.
Choose the Genotype Blood Test
Select the £160 20-biomarker genotype profile.
Select your collection option
Choose in-clinic phlebotomy for +£35 or an at-home phlebotomy visit for +£60.
Attend your appointment
A trained healthcare professional collects the required blood samples either at the clinic or at your home.
Laboratory analysis
Haemoglobin variants, sickle cell screening, blood group and Full Blood Count measurements are analysed.
Receive your results securely
Your completed Genotype Blood Test report is returned securely.
When Will I Receive My Results?
Results are generally expected within approximately 4 working days.
The complete report is released once the specialist haemoglobin testing and the other blood measurements have been completed and authorised.
Occasionally, an unusual haemoglobin pattern may require further analysis.
Understanding Your Results
The result should be interpreted as a combination of haemoglobin findings and general blood-cell measurements.
Haemoglobin Electrophoresis identifies the relative haemoglobin pattern present within the blood.
Haemoglobin A2 and Haemoglobin F provide additional information that can be relevant when investigating thalassaemia and other inherited haemoglobin conditions.
The Sickle Cell Screen Solubility Test provides screening information regarding Haemoglobin S.
Red-cell indices such as MCV, MCH, MCHC and RDW provide further information about red-cell size, Haemoglobin content and variation.
White-cell measurements and Platelets provide a broader picture of blood-cell health.
Blood Group is reported separately from the haemoglobin genotype findings.
Where an abnormal or complex haemoglobin pattern is identified, further genetic testing or specialist haematology review may be appropriate.
