Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.目标病原体阳性组(评价假阴性干扰) (1)经临床标准RT-PCR方法确诊为乙肝病毒、新冠病毒或结核分枝杆菌等感染者的阳性样本; (2)样本的Ct值在20-35之间(代表中高病毒载量,便于观察干扰物质对信号的抑制作用)。 2.疾病对照组(评价生物交叉反应/假阳性) 经RT-PCR或多重病原体检测确诊为其他相关呼吸道或系统性感染的样本,包括: (1)流感病毒(A型流感、B型流感); (2)新冠病毒(SARS-CoV-2)或其他呼吸道病毒(如RSV、腺病毒、肺炎支原体); (3)其他常见细菌感染(如结核分枝杆菌)。 3.特殊基质干扰组(评价内源性干扰) 临床外观检查显示具有特殊性状的样本,包括: (1)高粘液样本:含有大量粘蛋白的样本; (2)血性样本:肉眼可见或经潜血试验确认含有中浓度全血的样本。 4.药物干扰组(评价外源性干扰) 来源于正在接受抗病毒药物(如奥司他韦)治疗、常用感冒药物(如对乙酰氨基酚)或鼻腔喷雾剂治疗的患者,或在健康人基质中人工添加药物模拟样本(达到治疗峰浓度Cmax)。 5.一般条件 (1)年龄在1岁至85岁之间(涵盖高发人群,包括儿童和老年人),性别不限; (2)样本剩余体积>=200 μL,足以完成研究的复核与测试; (3)样本来源患者(或监护人)已签署知情同意书,允许剩余样本用于科学研究。

Inclusion criteria

1. Target Pathogen Positive Group (to evaluate false negative interference) (1) Positive samples confirmed by the clinical standard RT-PCR method as infected with hepatitis B virus, novel coronavirus, or Mycobacterium tuberculosis, etc.; (2) Samples with Ct values between 20-35 (representing medium to high viral load, which facilitates observation of the inhibitory effect of interfering substances on the signal). 2. Disease Control Group (to evaluate biological cross-reactivity/false positives) Samples confirmed by RT-PCR or multiplex pathogen detection as infected with other related respiratory or systemic infections, including: (1) Influenza virus (type A influenza, type B influenza); (2) Novel coronavirus (SARS-CoV-2) or other respiratory viruses (such as RSV, adenovirus, Mycoplasma pneumoniae); (3) Other common bacterial infections (such as Mycobacterium tuberculosis). 3. Special matrix interference group (to evaluate endogenous interference) Clinical appearance inspection shows samples with specific characteristics, including: (1) Highly viscous samples: samples containing a large amount of mucin; (2) Hematic samples: samples containing medium concentrations of whole blood, either visible to the naked eye or confirmed by occult blood test. 4. Drug interference group (to evaluate exogenous interference) Samples derived from patients undergoing treatment with antiviral drugs (such as oseltamivir), commonly used cold medications (such as acetaminophen), or nasal sprays, or samples in healthy individual matrices artificially spiked with drugs to simulate therapeutic peak concentrations (Cmax). 5. General conditions (1) Age between 1 and 85 years (covering high-risk populations, including children and the elderly), any gender; (2) Remaining sample volume >=200 μL, sufficient to complete study review and testing; (3) Patients (or guardians) from whom samples are sourced have signed informed consent, allowing residual samples to be used for scientific research.

排除标准:

1.样本严重变质或污染 样本保存不当导致明显浑浊、发霉或异味,可能含有大量细菌或化学污染,干扰CRISPR系统的反应。 2.严重溶血或深色样本 样本颜色过深(如深红色积血、深黄色高胆红素样本),其背景吸光度可能超出检测线性范围,影响信号测定。 3.采样介质不兼容 使用了含有强还原剂(如高浓度维生素C、二硫苏糖醇)或强螯合剂的非标准病毒采样管(VTM)。这些化学物质可能破坏样本的完整性,导致假阴性或信号丧失。 4.临床信息缺失 无法提供准确的RT-PCR参考结果,或无法追溯样本的感染类型。 5.混合感染无法区分主次(仅针对特异性评价) 当样本同时合并多种病毒或病原体(如双重阳性),会干扰特异性判断,应排除在交叉反应组之外,但可归入目标病原体阳性组。

Exclusion criteria:

1. Severely degraded or contaminated samples Improperly stored samples that are visibly turbid, moldy, or have an unusual odor may contain large amounts of bacteria or chemical contaminants, interfering with the CRISPR system's reaction. 2. Severe hemolysis or dark-colored samples Samples with overly dark colors (such as deep red hemo-concentrated blood or dark yellow high-bilirubin samples) may have background absorbance exceeding the detection linear range, affecting signal measurement. 3. Incompatible sampling media Using non-standard viral transport media (VTM) containing strong reducing agents (such as high-concentration vitamin C or dithiothreitol) or strong chelating agents. These chemicals may damage the integrity of the sample, leading to false negatives or signal loss. 4. Missing Clinical Information Unable to provide accurate RT-PCR reference results, or unable to trace the type of infection in the sample. 5. Mixed Infections Cannot Distinguish Primary and Secondary (Only for Specificity Evaluation) When a sample contains multiple viruses or pathogens simultaneously (such as double positives), this can interfere with specificity judgment and should be excluded from the cross-reactivity group, but can be included in the target pathogen positive group.
