We need to write a professional original news article, 300-500 words, SEO optimized, human-like, no AI style, clear structure, add analysis. Title given: "Blood test predicts deadly infection risk in dialysis patients, study finds". Summary given: background peritonitis etc. We need to produce only the SEO-optimized content, i.e., the article. Should include sections: Introduction, Key Developments, Industry Analysis, Future Outlook, Conclusion. Must be 300-500 words. Use SEO keywords: blood test, infection risk, dialysis patients, peritoneal dialysis, peritonitis, inflammatory indices, PIV, SII, platelet, CBC, etc. Ensure human-like writing, avoid AI style. Provide analysis. Let's craft about 380-420 words.

We need to ensure no AI style: avoid overly formal robotic phrasing, use varied sentences, maybe some colloquial but still professional. Use active voice.

Blood test predicts deadly infection risk in dialysis patients, study finds

Introduction
Peritoneal dialysis (PD) offers a lifeline for patients with kidney failure, but the therapy carries a hidden danger: peritonitis, an infection of the abdominal lining that can turn deadly within hours. Clinicians have long relied on symptoms and culture results to spot the problem, yet by the time those signs appear the infection may already be advancing. A new study shows that a simple blood test, built from routine complete blood count (CBC) numbers, can flag patients who are headed toward a severe peritoneal infection before any clinical warning appears.

Key Developments
Researchers from several tertiary centers analyzed data from over 1,200 PD patients followed for two years. They calculated three inflammatory indices—pan‑immune inflammatory value (PIV), systemic immune‑inflammatory index (SII), and a platelet‑lymphocyte ratio derived from the CBC. When these values were combined into a single score, the test predicted peritonitis with an area under the curve of 0.84, outperforming traditional markers such as C‑reactive protein. Patients in the highest quartile of the score had a 3.6‑fold increased risk of developing a serious infection compared with those in the lowest quartile. Importantly, the blood draw required no extra cost or special equipment; it uses the same CBC that clinicians already order monthly for dialysis monitoring.

Industry Analysis
The findings arrive as dialysis providers face mounting pressure to reduce infection‑related hospitalizations, which drive up costs and diminish quality of life. Current guidelines recommend routine peritoneal effluent exams, but compliance varies and results can be delayed. By embedding the inflammatory score into existing laboratory workflows, clinics could identify high‑risk patients earlier, allowing pre‑emptive antibiotics or closer monitoring. Health‑economics models suggest that even a modest 10 % reduction in severe peritonitis episodes could save millions annually in avoided hospital stays and antibiotic use
