Allergen Specific IgE Rapid Tests
Intended Use
Hypersensitivity: After the organism, initial response to certain
antigens, the immune response is enhanced when re-exposure to the
same antigen. When high antigen intake or organism immune response
is in a high level, due to the immune response is too strong, it
will cause specific immune response (mainly tissue injury). In1966,
Ishizaka found and proved that IgE antibody is the major antibody
mediated type I hypersensitivity. Since then, Screen the allergen
through detection of the specific IgE in the serum is an important
diagnosis method of allergic diseases.
This kit is used to qualitatively detect specific IgE antibody and
mainly used for the diagnosis of allergen screen.
Principles of the Tests
Panel 1: Artemisia & Ambrosia artemisiifolia pollen allergen,
dermatophagoides pteronyssinus & dermatophagoides farinae allergen,
cat hair allergen and dog hair allergen are coated on the T lines
separately and polyclonal goat anti-mouse IgG antibodies on C line
of the nitrocellulose membrane strip.
Panel 2 : Soybean allergen,chicken egg allergen,cow milk
allergen,cottonwood &willow & elm allergen are coated on the T
lines separately and polyclonal goat anti-mouse IgG antibodies on C
line of the nitrocellulose membrane strip. Colloidal gold labeled
goat anti-human IgE polyclonal antibody is the color substances
immobilized on conjugate pad. The sIgE antibodies in serum sample
combine with the gold labeled antibody to form colorful immune
complex and move alone the membrane strip by the action of
chromatography. The allergens pre-coated on the T lines can bind
the complex to form ‘allergen- sIgE antibodycolloidal gold labeled
mouse anti human sIgE’ and develop color. And the rest free
complexes are captured by the goat anti-mouse IgG antibody on the
control line and coloration. C line without coloration means the
result is invalid.
Negative results: Coloration on C line only.
Positive results: Coloration on C line and one or more T lines.
Main Constituent
The main components of kit:
Test card:
Test card 1: PVC case, glass fiber pad, nitrocellulose membrane
strip, Goat anti mouse IgG antibody, Artemisia&ambrosia
artemisiifolia pollen allergen, dermatophagoides pteronyssinus &
dermatophagoides farinae allergen, cat hair allergen and dog hair
allergen.
Test card 2: PVC case, glass fiber pad, nitrocellulose membrane
strip, Goat anti mouse IgG antibody, soybean allergen, chicken egg
allergen, cow milk allergen and cottonwood & willow & elm allergen
Each box contains:
1. Test card:25 tests / box
1 test contains isolated two test cards (Panel 1, Panel 2) and one
desiccating agent.
The test card of Panel 1 and Panel 2 is each containing 1 control
lines and 4
detection lines. It can detect 4 or more allergens. (Some Test
lines for mixed allergen)
2. Reference card: 1
3. Product instruction: 1
Storage conditions and the period of validity
Store at 2~30℃, dry places for 36 months.
Sample Request
1. To collect the venous blood by conventional method and separated
the serum or plasma as soon as possible to avoid hemolysis.
Hemolysis is not suitable for the test kit.
2. Samples can be stored at 4 ℃ if tests will be done within 7
days, otherwise stored at -20 ℃. No more than 3 times of
freeze-thaw with test sample.
3. The common heparin or sodium citrate anticoagulant does not
influence the
test results.
Test Procedure
1. Unseal the aluminum foil bag and put the test cards on a dry
horizontal work surface.
2. Add 100μL of serum or plasma sample into the sample well of test
card.
3. The test result must be observed in 25-30 minutes. The
observation is invalid after 30 minutes. Judge the result according
to the reference card.
Reference range and results and determine grade
Minimum detection limit:
Artemisia pollen allergen (1.0 IU/ml), ambrosia artemisiifolia
allergen (3.0 IU/ml), dermatophagoides pteronyssinus allergen (2.5
IU/ml), dermatophagoides farinae allergen (2.5 IU/ml), cat hair
allergen (2.0 IU/ml), dog hair allergen (2.0 IU/ml),soybean
allergen (2.5 IU/ml), the chicken egg allergen (3.0 IU/ml), cow
milk allergen (3.0 IU/ml), cottonwood allergen (2.5 IU/ml), willow
allergen (2.5 IU/ml), elm allergen (2.5 IU/ml).
The results determine whether chart1:
Negative: The test card appears one amaranth stripe on the c line,
which means the sample do not have the relative slgE antibodies to
T lines or it is lower than the minimum detection limit.
Positive: Appearing one purple stripe on the c line and one or more
amaranth stripes on the T lines. Judge the result according to the
Reference card.
Invalid: Develops color on T lines only, or no coloration on both T
lines and C line. In this case, re-detection should be done. Stop
using the batch of products and contact with local suppliers if
still invalid.
Test results explain
1. Appearing purple strip on the C line is internal control
standard of test card.
2. Four T lines on 1 test card may appear color in different degree
because of the different concentration of relative sIgE antibodies
in one sample. A very weak coloration should also be considered as
positive results.
Limitation
The kit is an assistant clinical diagnosis product. Its positive
results cover the allergen items designed in the card only. It does
not mean the patient is not allergic to other allergens out of the
test kit.
Product performance indicators
1. Minimum detection limit: artemisia pollen allergen (1.0 IU/ml),
ambrosia artemisiifolia allergen (3.0 IU/ml), dermatophagoides
pteronyssinus allergen (2.5 IU/ml), dermatophagoides farinae
allergen (2.5 IU/ml), cat hair allergen (2.0 IU/ml), dog hair
allergen (2.0 IU/ml), soybean allergen (2.5 IU/ml), the chicken egg
allergen (3.0 IU/ml), cow milk allergen (3.0 IU/ml), cottonwood
allergen (2.5 IU/ml), willow allergen (2.5 IU/ml), elm allergen
(2.5 IU/ml).
2. Sensitivity: Test 4 internal references serum (two positive, one
weak positive and one negative). The test of positive serum
references show purple strip on T lines clearly, light red stripe
for the weak positive serum and blank for the negative.
3. Positive coincidence rate: to internal positive reference (+/+)
=10/10.
4. The negative coincidence rate: to internal negative reference (-
/ -) =10/10
5. Precision (n=10): positive for all tests, and develop color
equably;
6. Cross Reactions: There is not cross reaction between allergens
of pannel1&2.
7. Interference factor: hemoglobin(≤10mg/ml), triglyceride (≤40.0mg
/ml), bilirubin(≤0.4mg/ml), and high concentration IgM or IgG do
not affect the test results.
Precautions
1. This kit is applicable to the detection in vitro only. Do not
use the expired products.
2. Do operate according to the instructions strictly.
3. To avoid the test card exposing in the air long time since it
can absorb moisture and affect the test results. Use test card
within 1 hour once open to atmosphere when the humidity is below
60%, or use it immediately if the humidity is higher.
4. Be attention to the potential biological risks. Wearing
necessary protective equipments, and dealing with waste as
infectious material.
