![]() ![]() Globulins are a heterogeneous group of proteins that are large, but variable in size. Albumin is also an important carrier protein. This oncotic pressure prevents water from diffusing from the blood into the tissues. Albumin is the smallest of these proteins, produced only by the liver, and the concentration of albumin molecules in the blood is greater than the concentration of globulin molecules.Īs a result, albumin accounts for about 80 percent of the oncotic pressure of the blood. The key types of proteins present in the serum are albumin and globulins. They may also screen for hepatitis B and C viruses.Q How does one interpret serum protein concentrations in dogs and cats?Ī Alterations in serum protein concentrations are commonly observed in a large number of diseases in dogs and cats. They will explain this to you before the test. So your doctor will routinely check for HIV as part of your blood tests. People with HIV (human immunodeficiency virus) have an increased risk of developing Hodgkin lymphoma. You can also have low albumin if you’ve been eating small amounts and are malnourished. This is a protein in the blood that can be low when you have some types of cancer. Bilirubin can cause yellowing of your skin and eyes (jaundice). Bilirubin can be raised if you have a problem with your liver or gallbladder. LFTs also look at the amount of bilirubin in the blood. They might be raised if you have a blockage in your liver or bile duct, or if you drink a lot of alcohol. LFTs look for levels of enzymes and proteins made by the liver or which are cleared by the liver. Liver function tests (LFTs) check how well your liver is working. Our kidneys remove them from our blood and get rid of them in our urine.Įlectrolytes are substances such as sodium, potassium, chloride and bicarbonate. Waste chemicals called urea and creatinine are produced by the body. These blood tests show how well your kidneys are working. The range of figures quoted as normal varies slightly between laboratories and also differs between men and women. ![]() There is a range of normal for blood counts. Symptoms of a low platelet count include abnormal bleeding, such as bleeding gums and nosebleeds. Platelets help clot the blood, for example after a cut.There are several different types of white cells, including neutrophils and lymphocytes. This can make you feel tired, short of breath and dizzy. If you have a low red cell count, your doctor might say you’re anaemic (pronounced a-nee-mic). Haemoglobin is the part of the cell that carries oxygen. Red cells carry oxygen around our bodies.feeling faint or fainting - tell the person doing your blood test if you're feeling lightheaded or dizzy at any timeĪ full blood count (FBC) measures the number of red cells, white cells and platelets in your blood.swelling (oedema) - ask your nurse, doctor or phlebotomist to avoid an arm that is swollen or has a risk of swelling.pain - this is normally mild and can last for a few minutes.bleeding and bruising - pressing hard when the needle is removed can help to stop it.Possible risks of having a blood testīlood sampling (phlebotomy) is a safe test. Some results might be available very quickly, such as a full blood count and kidney and liver function tests. Getting your resultsĪsk the phlebotomist, doctor or nurse when and how you will get your results. Look away when they’re taking the blood if you prefer. Tell your doctor, nurse or phlebotomist if you feel unwell. This helps to stop bleeding and bruising. They then take the needle out and put pressure on the area with a cotton wool ball or small piece of gauze for a few minutes. Once they have all the samples, they release the band around your arm. Next, they attach a small bottle or syringe to the needle to draw out some blood. They clean your skin and then put a small needle into your vein. You may need to clench your fist to make it easier to find a vein. They put a tight band (tourniquet) around your arm above the area where they take the sample. Let them know if you are afraid of needles, get unwell with the sight of blood or are allergic to plasters or latex. ![]() What happens?Ī doctor, nurse or phlebotomist (person specialised in taking blood) chooses the best vein to use. You can eat and drink normally before most blood tests. For fasting blood tests you need to stop eating and drinking beforehand. Blood tests can check your general health, for example your blood cell levels and how well your liver and kidneys are working. ![]()
