QuikRead go wrCRP+Hb

QuikRead go wrCRP+Hb is a fast and an easy to use test for quantitative determination of C-reactive protein (CRP) values in whole blood, serum and plasma and haemoglobin in whole blood with the QuikRead go instrument. The test gives reliably two results, the wide range CRP and the Hb, from one sample with one analysis.

Generally

Fast and measurement of C-reactive protein (CRP) can be critical in the management of a patient with symptoms of an infection. The easy-to-use QuikRead go wrCRP+Hb test can be performed near the patient, the CRP and Hb results are immediately available. The wide range CRP test allows the extension of CRP values from conventional use to testing e.g neonatal sepsis(1) as well as to predict disease severity in COPD(2) and aid in cardiovascular risk assessment(3). QuikRead go wrCRP is an efficient tool for point-of-care settings to guide the treatment decisions of healthcare professionals. Room temperature storage for unopened kit and small sample volume ease the everyday work of the healthcare professionals.

Haemoglobin measurement gives important information about the patient’s condition in both acute and basic healthcare settings. Changes in haemoglobin concentrations can be seen in several medial conditions, which make haemoglobin measurement one of the most commonly used tests. The causes behind abnormal haemoglobin levels should always be investigated further.

QuikRead go wrCRP+Hb is an efficient and reliable tool for point-of-care settings to guide the treatment decisions of healthcare professionals.

Regular use of QuikRead Controls is recommended.

The Controls available are:

  • Ultrasensitive CRP Control, with a concentration of approx. 2-3 mg/l 
  • QuikRead go wrCRP Control, with a concentration of approx. 30 mg/l
  • QuikRead go wrCRP Control High, with a concentration of approx. 80 mg/l
  • QuikRead go Hb Control

Specific features of CRP (C-reactive protein)

  • normally present in very low concentrations in the blood of healthy people; 99% have levels of <10 mg/l 1 and 90 % have levels < 3 mg/l2.
  • after birth concentrations are very low (0,1 mg/l) and there is a physiological rise during the first days of life (to approx. 2 mg/l)3
  • 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 h4, 5
  • 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, 6, 7
  • in a big part of septic neonates the concentrations are below 6 mg/l 8, 9, 10

About haemoglobin

Haemoglobin is the molecule that 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.

Frequently asked questions

I would like to start using the QuikRead go wrCRP+Hb tests. Which instrument software version I need on my QuikRead go instrument?
You should have the version 7.5.1.

I have updated my QuikRead go instrument into version 7.5.1 to start using the QuikRead go wrCRP+Hb test. However, now I noticed I have still some QuikRead go CRP+Hb kits in fridge. Can I use these kits still after the software update? 
Yes, in addition to the QuikRead go wrCRP+Hb tests, you can use the QuikRead go CRP and QuikRead go CRP+Hb kits with the QuikRead go instrument software version 7.5.1.

I accidentally left a QuikRead go wrCRP+Hb kit at room temperature for a weekend. Can I still use it?
Yes, you can use the kit. The unopened kit can be stored at cool or room temperature (2-25 ºC) until the expiry date marked on the kit label. After the first opening of the kit components, the cuvettes can be kept at room temperature (18-25) for 3 months. The reagent caps for 6 months. See more information in the package insert.

What happens if I accidentally use the 20 µl capillaries with the QuikRead go wrCRP+Hb test?
It is important to use only the 10 µl capillaries with orange stripe, which are inside the QuikRead go wrCRP+Hb test kit. The 20 µl capillaries have a blue stripe and are to be used with QuikRead go CRP test only. The instrument measures the haematocrit value and above the upper limit (75%), it will not give results. If you dispense twice the amount of sample, the instrument thinks the haematocrit value is double what it actually is. The HCT correction is able to correct only those sample results, which have hematocrit below 37.5%.
