You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Context: Chronic rhinosinusitis (CRS) is a heterogeneous disease with an uncertain pathogenesis. Group 2 innate lymphoid cells (ILC2s) represent a recently discovered cell population which has been implicated in driving Th2 inflammation in CRS; however, their relationship with clinical disease characteristics has yet to be investigated. The aim of this study was to identify ILC2s in sinus mucosa in patients with CRS and controls and compare ILC2s across characteristics of disease. A cross-sectional study of patients with CRS undergoing endoscopic sinus surgery was conducted. Sinus mucosal biopsies were obtained during surgery and control tissue from patients undergoing pituitary tumour resection through transphenoidal approach. ILC2s were identified as CD45(+) Lin(-) CD127(+) CD4(-) CD8(-) CRTH2(CD294)(+) CD161(+) cells in single cell suspensions through flow cytometry. ILC2 frequencies, measured as a percentage of CD45(+) cells, were compared across CRS phenotype, endotype, inflammatory CRS subtype and other disease characteristics including blood eosinophils, serum IgE, asthma status and nasal symptom score. 35 patients (40% female, age 48 17 years) including 13 with eosinophilic CRS (eCRS), 13 with non-eCRS and 9 controls were recruited. ILC2 frequencies were associated with the presence of nasal polyps (P = 0.002) as well as high tissue eosinophilia (P = 0.004) and eosinophil-dominant CRS (P = 0.001) (Mann-Whitney U). They were also associated with increased blood eosinophilia (P = 0.005). There were no significant associations found between ILC2s and serum total IgE and allergic disease. In the CRS with nasal polyps (CRSwNP) population, ILC2s were increased in patients with co-existing asthma (P = 0.03). ILC2s were also correlated with worsening nasal symptom score in CRS (P = 0.04).
Question: Are group 2 innate lymphoid cells ( ILC2s ) increased in chronic rhinosinusitis with nasal polyps or eosinophilia?
Solution: As ILC2s are elevated in patients with CRSwNP, they may drive nasal polyp formation in CRS. ILC2s are also linked with high tissue and blood eosinophilia and have a potential role in the activation and survival of eosinophils during the Th2 immune response. The association of innate lymphoid cells in CRS provides insights into its pathogenesis.
Why? The output says that ILC2s are elevated in patients with CRSwNP and that they may drive nasal polyp formtion in CRS. The output also says that ILC2s are linked with blood eosinophilia and hence, it completely answers the question on the basis of the information in the context.

New input: Context: Severe and potentially fatal hypersensitivity reactions to drugs, particularly antiepileptics, are clinically unpredictable. Recent evidence has revealed a strong and specific association between the implicated drug, the type of adverse reaction, and the particular HLA genotype. An urgent need exists for rapid diagnosis of HLA status to guide drug prescription; however, traditional HLA genotyping has a long turnaround time, is expensive, and is available only in specialized centers. We tested the feasibility of the loop-mediated isothermal amplification (LAMP)-based approach to detect a specific HLA genotype. As an example, we used B*1502, an HLA allele strongly associated with carbamazepine-induced Stevens-Johnson syndrome/toxic epidermal necrolysis, and validated the assay's application as a simple, accurate, rapid, and low-cost blood test for use in both clinical and bedside settings.", 'We evaluated B*1502 status with the new LAMP method and compared the results with those obtained by sequence-based typing (SBT) (n = 250) and by sequence-specific primer PCR (SSP-PCR) (n = 200) for 450 samples of DNA (n = 50) and blood (n = 400) from a hematology laboratory.', 'LAMP results showed 100% concordance with both SBT and SSP-PCR results, confirming that LAMP detection of a specific HLA genotype (B*1502 in this case) is an accurate method. All results were available within 1 h.\Question: Does new testing approach in HLA genotyping help overcome barriers in effective clinical practice?
Solution:
Our study confirmed that the new LAMP method for detecting a specific HLA genotype is simple, inexpensive, accurate, and rapid, and may be of help in overcoming barriers in effective clinical practice.
