【什么是質(zhì)控品】

1. 質(zhì)控品的來源： 
  質(zhì)控品的來源同校準(zhǔn)品大致相同，廠商可能會(huì)更具自己的要求添加了很多物質(zhì)，此時(shí)有些物質(zhì)的添加量常常達(dá)到病理狀態(tài)的高濃度，在應(yīng)用于某一項(xiàng)目時(shí)，對這個(gè)項(xiàng)目來說基質(zhì)效應(yīng)將更大。

2. 定值方法： 
  有些廠商會(huì)給自己的標(biāo)準(zhǔn)品定一個(gè)定值范圍，這個(gè)定值范圍是由廠商聯(lián)合幾家使用同樣檢測系統(tǒng)的臨床用戶，僅多次測定得出的均值。此時(shí)如果將該質(zhì)控品應(yīng)用于另一個(gè)檢測系統(tǒng)，由于方法學(xué)的不同，可能得出同廠商給出值有較大差異的值。此時(shí)不能認(rèn)為該檢測系統(tǒng)的準(zhǔn)確度不佳。此時(shí)需要強(qiáng)調(diào)的是檢測系統(tǒng)都是用來測定新鮮血清的，不是用來測定質(zhì)控品或其他物質(zhì)的。檢測系統(tǒng)只有在檢測新鮮血清是得出的結(jié)果才具有溯源性。不同檢測系統(tǒng)之間只有在檢測新鮮血清時(shí)才具可比性。

我司還提供其它進(jìn)口或國產(chǎn)試劑盒：登革熱、瘧疾、流感、A鏈球菌、合胞病毒、腮病毒、乙腦、寨卡、黃熱病、基孔肯雅熱、克錐蟲病、違禁品濫用、肺炎球菌、軍團(tuán)菌、化妝品檢測、食品安全檢測等試劑盒以及日本生研細(xì)菌分型診斷血清、德國SiFin診斷血清、丹麥SSI診斷血清等產(chǎn)品。

先天性弓形蟲病的臨床表現(xiàn)復(fù)雜。多數(shù)嬰兒出生時(shí)可無癥狀，其中部分于出生后數(shù)月或數(shù)年發(fā)生視網(wǎng)膜脈絡(luò)膜炎、斜視、失明、癲癇、精神運(yùn)動(dòng)或智力遲鈍等。下列不同組合的臨床表現(xiàn)：視網(wǎng)膜脈絡(luò)膜炎、腦積水、小頭畸形、無腦兒、顱內(nèi)鈣化等應(yīng)考慮本病可能。后天獲得性弓形蟲病病情輕重不一，免疫功能正常的宿主可表現(xiàn)急性淋巴結(jié)炎zui為多見，約占%。免疫缺損者如艾滋病、、惡性腫瘤（主要為霍杰金病等）常有顯著全身癥狀，如高熱、斑丘疹、肌痛、關(guān)節(jié)痛、頭痛、嘔吐、譫妄，并發(fā)生腦炎、心肌炎、肺炎、肝炎、胃腸炎等。眼弓形蟲病多數(shù)為先天性，后天所見者可能為先天潛在病灶活性所致。臨床上有視力模糊、盲點(diǎn)、怕光、疼痛、淚溢、中心性視力缺失等，很少有全身癥狀。炎癥消退后視力改善，但常不*恢復(fù)。可有玻璃體混濁。檢查.病原學(xué)檢查將可疑病畜或死亡動(dòng)物的組織或體液，做涂片、壓片或切片，甲醇固定后，作瑞氏或姬氏染色鏡檢可找到弓形蟲滋養(yǎng)體或包囊。.用CR方法檢測特異性核酸.血清學(xué)診斷間接熒光抗體試驗(yàn)、間接血凝抑制試驗(yàn)、酶聯(lián)免疫吸附試驗(yàn)和補(bǔ)體結(jié)合試驗(yàn)檢測特異性IgM、IgG、IgA抗體或血清循環(huán)抗原。蟲的裂殖子( bradyzoites )會(huì)於貓的腸道壁內(nèi)進(jìn)行增殖，但通常都是無任何癥狀的，僅有少數(shù)病例會(huì)引發(fā)輕微下痢。
The clinical manifestations of congenital toxoplasmosis are complex. Most babies are asymptomatic at birth, and some of them develop retinochoroiditis, strabismus, blindness, epilepsy, mental activity, or mental retardation several months or years after birth. The following different combinations of clinical manifestations: retinal choroiditis, hydrocephalus, microcephaly, no brain children, intracranial calcification, etc. should consider the possibility of this disease. Acquired acquired toxoplasmosis differs in severity, and hosts with normal immune function can exhibit acute lymphadenitis, which accounts for approximay %. Immunocompromised persons such as AIDS, malignancies (mainly Hodgkin's disease, etc.) often have significant systemic symptoms, such as high fever, rash, myalgia, joint pain, headache, vomiting, sputum, and encephalitis, myocarditis, and pneumonia. Hepatitis, gastroenteritis, etc. Toxoplasmosis of the eye is mostly congenital, and the findings of the day after tomorrow may be due to the activity of congenital underlying lesions. There are clinically blurred vision, blind spots, photophobia, pain, tears, and lack of central vision. There are few systemic symptoms. Visual acuity improves after inflammation subsides, but often does not fully recover. There may be vitreous opacities. Exam. Etiological examination Tissues or body fluids of suspected diseased animals or dead animals are smeared, compressed or sliced. After methanol fixation, microscopic examination of Wright's or Gissie's stain can be used to find Toxoplasma gondii trophozoites or cysts. Detection of specific nucleic acids using the CR method. Serological diagnosis Indirect fluorescent antibody assays, indirect hemagglutination inhibition assays, enzyme-linked immunosorbent assays, and complement fixation assays detect specific IgM, IgG, IgA antibodies, or serum circulating antigens. The bradyzoites of the worms proliferate within the cat's intestinal wall, but they are usually free of any symptoms. Only a few cases can cause slight diarrhoea.
