莱姆病(Lyme)快速检测试剂盒

Lyme Disease IgG  

莱姆病(Lyme disease)是由伯氏疏螺旋体所致的自然疫源性疾病，又称莱姆疏螺旋体病(Lyme borreliosis)。临床表现主要为皮肤、心脏、神经和关节等多系统、多脏器损害。 本病为全球性疾病，由来已久。1900年欧洲的皮肤病文献中已有慢性游走性红斑(erythema chronicum migrans，ECM)的记载，1905年美国康涅狄格州开始有ECM的病例报道。1975年又在该州的Lyme镇发生曾被诊断为青少年类风湿关节炎的疾病流行，称为“Lyme关节炎”。1978年证明该病是由硬蜱叮咬传播的一种多系统受累的传染病，所以称为莱姆病。1982年从蜱体内分离到螺旋体，1984年证实此病原体属包柔螺旋体属(Borrelia)，亦称疏螺旋体属。由于本病分布广，传播快，致残率高。

PRINCIPLE OF THE ELISA ASSAY The Diagnostic Automation B. burgdorferi ELISA test system is designed to detect IgG class antibodies to B. burgdorferi in human sera. Wells of plastic microwell strips are sensitized by passive absorption with B. burgdorferi antigen. The test procedure involves three incubation steps: 1. Test sera (properly diluted) are incubated in antigen coated microwells. Any antigen specific

 antibody in the sample will bind to the immobilized antigen. The plate is washed to remove

 unbound antibody and other serum components. 2. Peroxidase Conjugated goat anti-human IgG (γ chain specific) is added to the wells and the

 plate is incubated. The Conjugate will react with IgG antibody immobilized on the solid phase

 in step 1. The wells are washed to remove unreacted Conjugate. 3. The microwells containing immobilized peroxidase Conjugate are incubated with peroxidase

 Substrate Solution. Hydrolysis of the Substrate by peroxidase produces a color change. After

 a period of time the reaction is stopped and the color intensity of the solution is measured

 photometrically. The color intensity of the solution depends upon the antibody concentration in

 the original test sample.

SPECIMEN COLLECTION 1. It is recommended that specimen collection be carried out in accordance with NCCLS

 document M29:Protection of Laboratory Workers from Infectious Disease. 2. No known test method can offer complete assurance that human blood samples will not

 transmit infection. Therefore, all blood derivatives should be considered potentially infectious. 3. Only freshly drawn and properly refrigerated sera obtained by approved aseptic venipuncture

 procedures should be used in this assay (6, 7). No anticoagulants or preservatives should be

 added. Avoid using hemolyzed, lipemic, or bacterially contaminated sera. 4. Store sample at room temperature for no longer than 8 hours. If testing is not performed within

 8 hours, sera may be stored between 2° and 8°C for no longer than 48 hours. If delay in

 testing is anticipated, store test sera at –20°C or lower. Avoid multiple freeze/thaw cycles that

 may cause loss of antibody activity and give erroneous results.
