ASPERGILLUS FUMIGATUS(M3) AND FLAVUS(M228) IGG

Infectious Serology

The ImmunoCAP Specific IgG is an immunoassay for the quantitative measurement of antigen specific IgG antibodies to A. fumigatus and A. flavus in serum. It is intended for in vitro diagnostic use to assess IgG associated immune response using Phadia 250 instrument.

Allergic bronchopulmonary aspergillosis (ABPA) and allergic bronchopulmonary mycosis (ABPM) involve the colonisation by Aspergillus fumigatus and other fungal species which elicit a characteristic humoral immune response to antigens or allergens of these fungi. A. fumigatus and A. flavus are opportunistic pathogens in humans. They can cause mild infections but also life-threatening diseases in those who are immunocompromised.

Sample Type:

Tube Type:

Serum (Gold and red cap);

Heparin (Green cap) or EDTA (Lavender cap) Plasma

Temperature: + 4ºC

Turnaround Time:

4 working days

Sample Stability:

Whole blood: unknown.

Separated: RT 7 days

7 days @ + 4ºC or longer @ -20 ºC

Instrument / Procedure:

Fluoroenzyme immunoassay (Phadia 250)

Units:

mgA/L

Reference Range:

<14   Negative                                      

14-27 Equivocal                                    

>27   Positive

                                     

All equivocal or positive screening result is to be confirmed by confirmatory technique.

According to a review of the literature, cut-offs in diseased population (ABPA or aspergillosis) vary between 27 and 50 mgA/L. A grey zone was defined for values between 14 and 27 mgA/L with 14 mgA/L representing the threshold    

triggering confirmation of aspergillosis serology using the ASPERGILLOSIS IgG Western Blot (LDBIO).

SAMPLE REQUIREMENTS FOR COAGULATION TESTS

PROCEDURE

Sample Requirements and Collection

  • Patients should be relaxed pre-venepuncture. Excessive stress and exercise will increase FVIII, vWF antigen and fibrinolysis. Venous occlusion should be avoided.
  • Difficult venepuncture with trauma may lead to platelet activation with release of PF4 fromalpha granules.
  • Venous blood should be collected into coagulation tubes containing Sodium Citrate 3.2%, 0.105M, 3ml.
  • Specimens must be mixed immediately post venepuncture to avoid clot activation, by GENTLY inverting the tubes 5 to 10 times.
  • The ratio of whole blood to anticoagulant is crucial. Under-filled specimens will not be processed as over- or under-filled tubes can adversely affect results.
  • Any warfarin treatment should be mentioned on the request form.

Transportation and Storage

  • PT/INR specimens should ideally be analysed within 12 hours of collection and transported to the laboratory at room temperature.
  • APTT and Fibrinogen should ideally be analysed within 4 hours of collection. Where this is not possible please centrifuge at room temperature (RT) @3000rpm (1500g) for at least 15 minutes, and then carefully remove the plasma from the cells, transfer to a fresh plastic plain tube and freeze at -20oC.
  • Non-frozen coagulation specimens should be transported at RT ASAP to avoid deterioration of labile factors V and VIII.
  • Collection of blood through intravenous lines that have been previously flushed with heparin should be avoided. In the event blood is drawn from an indwelling catheter, the line should be flushed with 5ml of saline, and the first 5ml of blood or 6 times the line volume be drawn off and discarded before coagulation tube is filled.

Plasma Sample Stability (CLSI H21-A5)

  • PT 24 hours @ RT or 2 weeks @ -20oC
  • APTT 4 hours @ RT or 2 weeks @ -20oC & 12 Months @ -70oC
  • Fibrinogen - 4 hours @ RT `
