Description
Technical field
The utility model belongs to Eaton agent pneumonia MP detection fields, and MP non-specificity things can be intercepted more particularly, to one kind
The detection card of matter and hemoglobin.
Background technology
Eaton agent pneumonia (mycoplasma pneumonia, abbreviation MP) is also known as primary atypical pneumonia, condensation collection sun
Property pneumonia, be " SARS " in one kind, be as caused by mycoplasma infection, in interstitial pneumonia and bronchiolitis
Sample changes, and accounts for the 10%%~40% of community-acquired pneumonia in children, pulmonary lesion is in confluent bronchopneumonia, chromic fibrous lung
Inflammation, with bronchitis.Alveolar has a small amount of inflammatory exudate, and focal atelectasis, pulmonary consolidation and pulmonary emphysema can occur.Clinical manifestation
The lung inflammation acutely coughed for intractable.MP is one of Childhood pneumonia and the important pathogen of other respiratory tract infection.Lung
Scorching mycoplasma can cause tonsillitis, rhinitis, tympanitis, tracheitis, bronchiolitis, pneumonia；Child suffers from respiratory tract more
Infection；School age youngster suffers from an inflammation of the lungs more.
The method of usual pneumonia diagnosis has medical imaging, is separately cultured and Serologic detection.ELASA in serology
(ELISA) is common methods, and about 1-2 hours, collaurum product, small volume are easy to use often, it is not necessary to large-scale instrument
Device, try out in various occasions, and single detection 10-20 minutes.The expense of detection is saved, while shorter time goes out knot
Fruit, doctor can be coordinated to make diagnosis, make patient's obtaining medical treatment earlier, early rehabilitation.
In mycoplasma pneumoniae IgM antibody detection collaurum product, nonspecific interference material is had, shadow can be caused to experiment
Ring, make accuracy, false positive increases.In order to remove it, usual way is, into the formula of sample pad, it is appropriate to add
Albumen, for combine non-specific material, play a part of interception, still, experiment development, it is found that, be added to
The long period is needed to dry after in sample pad, it has not been convenient to quick detection, and utilization rate is low, and high-volume is prepared and small lot
Larger error occurs in preparation；Reincarnation postpartum, it is found that, the inventory of such a method consumption can be very big, once occur larger
Error, cost also can be in the growth of geometry times.In addition, also there is whole blood test test paper in collaurum in the market.This test strips need
A layers of blood separating film added at sample pad end, or add anti-human RBC in sample pad and play interception hemoglobin, make nitric acid fine
The background race sample for tieing up plain film is clean.Two kinds of products at the moment respectively have advantage and disadvantage, and anti-human RBC antibody is added into sample pad, though can
To intercept hemoglobin, still, addition needs to adjust repeatedly every time, moreover, there is small error when preparing, then run
During sample, background can be slightly red, and unnecessary trouble is caused to experimental result.Although and hemofiltration film can largely remove it is blood red
Albumen so that clean background, still, material are thicker, it is also necessary to connect each position with adhesive tape, play stable effect, more
It is cumbersome.
