What are some simple blood tests
Blood and blood diagnostics
At the doctor's and in the clinic, blood tests can help detect or treat a disease. In some cases, complex laboratory analyzes are important for the quality of the results. But rapid tests and self-tests also play an important role. For example, they are even used at patients' homes to monitor the progress of illnesses under therapy or from the therapy itself.
Point of Care blood tests
Point-of-Care-Testing (POCT) stands for laboratory diagnostic procedures that doctors or medical staff carry out directly at the bedside or in the practice in the immediate vicinity of the patient with special devices. They use rapid tests for this near-patient diagnosis. These are now available for a number of different blood values. The possibilities range from the simple determination of blood sugar to the analysis of blood coagulation values. Because the blood samples do not have to be transported to a distant laboratory, the test results are quickly available to the doctors. In some cases, this allows you to find out more quickly what the patients are suffering from or what treatment they need.
For example: rapid heart attack tests
Not all people with a heart attack experience the typical symptoms such as pressure on the chest and pain in the arm. Some report aching chest or nausea, others do not see a doctor until a few hours after the symptoms start. In such cases, the doctor can examine a blood sample for certain protein building blocks that indicate a heart attack - and in an emergency, admit it to the hospital straight away.
Prof. Dr. Chandler:
“For near-patient diagnostics, the blood sample must be analyzed within a very short time, as the components of the blood are not stabilized by certain procedures such as centrifugation, treatment with anticoagulants or freezing. Getting results right away is important in some clinic or doctor's office situations. That is the strength of rapid tests. However, the quality of the results is somewhat limited. This is why quality-assured diagnostics should always follow in a laboratory if possible. For diabetes. "
Blood tests as self tests
For some diseases such as diabetes, coagulation disorders or cardiovascular diseases, blood tests help patients to manage their diseases in everyday life. Diabetics, for example, use mobile measuring devices to determine their current blood sugar level after a small spade on the fingertip. In this way, you can check whether you need to inject enough insulin or adjust the dose so that your blood sugar level remains stable. Patients who have to take anticoagulant medication such as Marcumar because of cardiac arrhythmias or a coagulation disorder, for example, monitor the success of the treatment by means of self-tests. To do this, they determine the INR (International Normalized Ratio) value from a drop of blood. It tells you how long it takes the blood to clot. The higher the value, the slower the blood coagulates.
Blood tests in the laboratory
In addition to POCT procedures, resident doctors and hospital doctors make use of a wide range of options offered by accredited medical laboratories. The external laboratory services also benefit the hospitals that no longer have their own large specialist laboratory medicine department. In larger central laboratories, complex and extensive special test procedures can also be carried out promptly.
