QuikRead go CRP+Hb
QuikRead go CRP+Hb is a fast and easy-to-use test for quantitative determination of C-reactive protein (CRP) values in whole blood, serum, and plasma and haemoglobin (Hb) in whole blood with the QuikRead go instrument. The test gives reliably two results, CRP and Hb, from one sample with one analysis.
Accurate measurement of C-reactive protein (CRP) can be critical in the clinical management of a patient with symptoms of infection. QuikRead go CRP+Hb test helps to identify patients who benefit from antibiotics and it is valuable in monitoring the treatment outcome
Hemoglobin measurement gives important information about the patient’s condition in both acute and basic healthcare settings. Changes in hemoglobin concentrations can be seen in several medical conditions which make hemoglobin measurement one of the most commonly used tests.
QuikRead go CRP+Hb is an efficient and reliable tool for point-of-care settings to guide the treatment decisions of healthcare professional.

About C-reactive protein (CRP)
CRP (C-reactive protein) is an acute-phase protein synthesised in the liver. Production of CRP is rapidly induced in response to infection, inflammation and tissue injury. Measurement of CRP may be helpful in the clinical management of patients with symptoms of infection. When evaluated in the light of the patient’s clinical condition, measurement of CRP can assist in differentiating between bacterial and viral infections and in rationalising antibiotic therapy. Monitoring CRP levels also provides an objective means of assessing treatment response as CRP levels fall rapidly as a result of effective therapy.
Specific features of CRP
- normally present in very low concentrations in the blood of healthy people; 99% have levels of < 10 mg/l1
- uncomplicated viral infections mostly induce (with some exceptions) a very modest elevation or none at all1
- in bacterial infections, concentrations increase markedly1
- elevated concentrations can be detected within 6 - 12 h after onset of an inflammatory stimulus, reaching maximum within 24 - 48 h2,3
- rise in concentrations corresponds to severity of infection1
- concentrations fall rapidly when the patient responds to antibiotic treatment1
- normalisation of the concentration may indicate that the duration of the treatment has been sufficient and the treatment can be discontinued1,4,5

Haemoglobin is the molecule which contains iron transports oxygen in the blood. It binds oxygen in the lungs, transports it to tissues and returns carbon dioxide from tissues to the lungs. Haemoglobin has an important role in the body’s iron cycle and it contains most of the functional iron in the body.
If a patient has anemia the blood haemoglobin or red blood cell concentration is below recommended levels. Anemia has many different causes but iron deficiency, which causes iron deficiency anemia, is the most common cause in the Western world. It should be remembered that anemia is more of a symptom than a disease. Haemoglobin tests may help diagnose anemia but the cause of anemia has to be investigated.

Antibiotics and CRP
Antibiotics are a cornerstone of the management of bacterial infections. 80 - 90% of antibiotics are prescribed in primary care, and up to 80% of these are used to treat acute respiratory tract infections1. It is estimated that approximately 50% of all antibiotic prescriptions are unnecessary2. Although most of both upper and lower respiratory tract infections are self-limiting and caused by viruses, antibiotics are frequently used to treat these conditions. Unnecessary and inappropriate use of antibiotics favours the emergence and spread of resistant bacteria. Antibiotic resistance is a major public health concern, which could cause harm to a large number of patients worldwide if infections are no longer susceptible to common medicines used to treat them. Therefore, antibiotics should be used with caution and only when necessary3.
The use of antibiotics in primary care varies considerably between countries, which is unlikely to be caused by differences in the frequency of bacterial infections. There is a clear correlation between the use of antibiotics and the emergence of antibiotic resistance4-6. As stated by the World Health Organization (WHO)3, restricting an inappropriate and excessive antibiotic use is important to slow down or even reverse the development of antibiotic resistance.
The QuikRead go CRP test helps healthcare professionals to identify those patients who need - and particularly those who do not need - antibiotic therapy. It is also important to know whether the antibiotics will affect the course of the illness7,8. QuikRead go CRP is useful for following up the effect of treatment. With accurate information, patients can be more easily reassured that symptomatic treatment will be sufficient. On the other hand, a high QuikRead go CRP reading would suggest a bacterial infection requiring antibiotic treatment.

Frequently asked questions
I opened the lid of a cuvette but I did not use the cuvette immediately. How long is the cuvette usable?
You should use the cuvette within 2 hours of opening it.
Can I use CRP controls with the QuikRead go CRP+Hb test kit?
Yes, you can use the same CRP controls with the QuikRead go CRP and QuikRead go CRP+Hb tests. The target values are valid for both tests.
Do I get a hemoglobin result automatically from every measurement if I use QuikRead go CRP+Hb test?
Yes, you automatically get both CRP and hemoglobin results each time from whole blood samples. If plasma or serum samples are used, you only receive a CRP result. This is because plasma and serum samples do not contain red blood cells and, therefore, do not contain hemoglobin.
Is it enough to take only one capillary sample (not two replicates) to get a reliable hemoglobin result?
We have evaluated the difference between parallel samples with the QuikRead go CRP+Hb test and we do not see any need for two or more parallel samples. The Hb results received with the QuikRead go CRP+Hb test are comparable to laboratory results and to the gold standard methods, and they require a single sample only. It is always important to pay attention to proper sampling technique.
