To rule out anemia or infection
Thyroid Animating Chemical is delivered in the pituitary organ and animates the thyroid organ to create thyroid chemicals thyroxine (T4) and triiodothyronine (T3).
Elevated degrees of TSH show an underactive thyroid while low levels demonstrate an overactive thyroid. In essential pituitary disappointment, a low TSH will be related with an underactive thyroid.
Triiodothyronine (T3) is one of two thyroid chemicals created by the thyroid organ. Most T3 is bound to protein in the blood. It assists with controlling digestion. Free T3 estimates the degree of T3 that is free, or unbound to protein.
Thyroxine (T4) is one of two chemicals created by the thyroid organ. Most T4 is bound to transporter proteins in the blood – this test estimates the degree of T4 which is free, or unbound, circling in your blood.
Elevated degrees of free thyroxine can demonstrate an overactive thyroid while low levels can show an underactive thyroid.
Vitamin D is actually a hormone which is activated by sunshine on your skin. Many people in the UK do not produce enough Vitamin D, especially in the winter months with fewer daylight hours Vitamin D is essential for bone strength as it helps your intestines absorb calcium.
However, it is thought that vitamin D also plays an important role in immune function, as well as in many chronic diseases and mental health.
In winter months, if your levels are found to be low, you may wish to take a supplement.
Vitamin B12 is part of the B complex of vitamins
The body is unable to make them itself and so instead must take them in through the diet
It contributes to your red blood cells metabolism and organ function
An essential vitamin for red blood cell production, DNA synthesis, and energy. Low levels can lead to fatigue, anemia, and poor concentration.
Ferritin is a protein which stores iron in your cells for your body to use later. Measuring ferritin levels gives us a good indication of the amount of iron stored in your body.
Low levels of ferritin can indicate anemia which can be caused by excessive or chronic bleeding, poor absorption of iron or too little iron in the diet.
Raised ferritin levels can indicate iron overload syndrome (haemochromatosis) or any kind of liver damage. It is also a marker of infection and inflammation.
A blood test that measures iron levels and your body’s ability to transport it, helping diagnose iron deficiency or overload—common causes of fatigue and anemia.
C-Reactive Protein (CRP) is an inflammation marker
it does not identify where the inflammation is located. High Sensitivity CRP (CRP-hs) is a test which is used to detect low-level inflammation which is thought to damage blood vessels which can lead to a heart attack or stroke.
A hBA1C test is used to determine the amount of glucose in the blood, this is often used as a in screening for prediabetes or diabetes.
Bilirubin is a yellow pigment that’s in everyone’s blood and stool. Sometimes the liver can’t process the bilirubin in the body. This can be due to an excess of bilirubin, an obstruction, or inflammation of the liver. When your body has too much bilirubin, In both adults and children, symptoms related to high bilirubin can involve jaundice, a yellowing of the skin or eyes, fatigue, itchy skin, dark urine, and low appetite.
An alkaline phosphatase level test (ALP test) measures the amount of alkaline phosphatase enzyme in your bloodstream
Alanine transferase (ALT) is an enzyme which is produced by the liver and can indicate liver damage caused by alcohol, drugs or viruses (hepatitis). Small amounts of ALT are normal, but raised levels may indicate that your liver is inflamed.
Elevated levels of ALT can also be caused by recent vigorous exercise.
Creatine kinase (CK) is an enzyme chiefly found in the brain, skeletal muscles, and heart. An elevated level of creatine kinase is seen in heart attacks, when the heart muscle is damaged, or in conditions that produce damage to the skeletal muscles or brain.
The level of Creatine Kinase in the blood is measured to assess muscle damage – it can rise very quickly after muscle trauma, but will begin to lower as the damage is repaired. If Creatine Kinase continues to rise it indicates that muscle damage is not being repaired.
Gamma-glytamyl transpeptidase (GGT) is an enzyme which is found in hepatocytes and biliary epithelial cells. GGT may be high in liver disease. Gamma GT is also used to diagnose alcohol abuse as it is raised in 75% of long term drinkers.
Urea is a waste product it is produced as your body digests protein and is carried by the blood to your kidneys, which filter the urea out of the blood and into urine.
This test looks at how well your kidneys are functioning.
High urea levels suggest poor kidney function. This may be due to acute or chronic kidney disease. However, there are many things besides kidney disease that can affect urea levels such as stress, recent heart attack or severe burns; bleeding from the gastrointestinal tract; conditions that cause obstruction of urine flow or dehydration.
Low urea levels are not common and are not usually a cause for concern. They can be with low protein diets, excess hydration malnutrition or liver failure. Low urea levels are also seen in normal pregnancy.
Creatinine is a chemical byproduct molecule generated from muscle metabolism.
Measuring Creatinine is an accurate marker of your kidney function.
Higher than usual levels of Creatinine can be caused by a high intake of Creatinine supplements, animal protein and vigorous exercise however it can also mean that your kidneys are not functioning properly.
Lower Creatinine levels can usually be caused by a reduction in muscle mass, low protein diet. It can also be an indication that your kidneys are not functioning correctly.
The estimated glomerular filtration rate (eGFR) assesses how well the kidneys are working by estimating the amount of blood filtered through the kidneys. The glomeruli are tiny filters in the kidneys responsible for removing waste products. If these filters do not do their job properly, kidney function can be impaired. The eGFR calculation is an estimate of actual glomerular filtration rate, calculated using your age, gender, ethnicity, and serum creatinine levels.
