A CLOSER LOOK AT THE BLOOD TESTS WE CARRY OUT

Mary GarlandWe have a fully-equipped laboratory at our clinic in Pulborough.

Our laboratory scientist, Mary Garland, tests the blood on the day of collection and highlights any results that fall outside the 'normal' ranges.

NB a small variation from the ‘normal’ ranges showing on your report sheet will not necessarily be considered significant.  Your nurse will advise you if further investigation is necessary.

 

Red Blood CellsThe blood tests fall into 3 categories: (click on each link below to jump to a brief explanation)

1. BIOCHEMISTRY - The chemical make-up of your blood
2. LIPID PROFILE - Reflects the fats & cholesterol in your blood
3. HAEMATOLOGY - The health of your blood cells

4. LIVER FUNCTION

 

 

 

 

1. BIOCHEMISTRY

Kidney related tests:

- Urea
- Creatinine

Your kidneys filter your blood, creating waste products which become urine.
These tests can indicate problems with your kidney function and other general illnesses.

Fasting glucose test:

This test can indicate diabetes.
This might indicate that your body cannot regulate sugar and further tests may be necessary.

Amylase test:

This enzyme test is used to uncover some liver and pancreatic problems.

Alkaline phosphotase:

This general enzyme is found in most body tissues.
High levels can be linked with liver, bile duct or bone problems.
Levels increase with age and medication.

Uric acid:

High levels can indicate renal stones and/or gout.  Decreased levels may relate to kidney problems.

Calcium:

This is NOT an indication of bone density or osteoporosis.
Calcium is an important element in our body for nerves, enzymes, muscles and blood health.

PSA:

This is a test for prostate specific antigen in the blood.  It is NOT a foolproof test for prostate cancer.

 

 

 

2. LIPID PROFILE

Total cholesterol:

This blood fat (lipid) is associated with heart disease.
However, other risk factors are considered – eg family history, blood pressure, diabetes, weight, smoking and stress – when advising on further management.

HDL (high density lipoprotein) – “good cholesterol”:

This takes cholesterol from the blood vessels and deposits it in the liver to be broken down.

LDL (low density lipoprotein) – “bad cholesterol”:

This takes cholesterol from the liver and deposits it in the blood vessels.

Triglycerides:

A different fat to cholesterol, it contributes to heart disease when raised.
Raised levels can be associated with obesity, diabetes and alcohol.

Total cholesterol / HDL ratio:

This ratio is an indication of the risk of heart disease.

 

 

 

3. HAEMATOLOGY

Full blood count:

- WBC (white cell count)
- RBC (red cell count)
- Haemaglobin
- Platelets

These tests look at the health of your blood and immune system, as well as the ability of the cells to carry oxygen.

 

 

 

4. LIVER FUNCTION

Liver related tests:
- GGT
- GOT(AST)
- GPT
- Bilirubin
- Albumin
- Total Protein

One role of your liver is to remove toxins from your body.
These tests are designed to highlight problems with your liver and related organs.
Raised levels can be linked to medication or alcohol consumption and further investigations may be required.
