Top 10 New Diagnostic Tests Every Clinician Should Know in 2025
Author: Dr. Pawan Gaba | Published by: Lab Decoded | Date: May 2025
In 2025, the world of diagnostics is being transformed by emerging technologies that enable faster, less invasive, and more accurate disease detection. For clinicians and laboratory professionals, staying updated with the latest diagnostic innovations is not just an option—it's a necessity. In this blog post, we explore ten breakthrough tests reshaping healthcare globally.
1. pTau217 Blood Test – Early Detection of Alzheimer’s
This blood-based test measures phosphorylated tau (pTau217), a hallmark of Alzheimer’s pathology. It has shown >90% accuracy in differentiating Alzheimer’s from other dementias—even before symptoms begin.
Clinical Impact: Shifts diagnosis from invasive CSF and PET scans to a simple blood draw.
Use in Practice: Ideal for memory clinics and neurologists managing early cognitive decline.
2. Fujifilm SILVAMP TB LAM – Urine Test for TB in HIV
This rapid, urine-based TB diagnostic test is revolutionizing care in HIV+ patients, especially in resource-limited settings. It detects the LAM antigen of Mycobacterium tuberculosis within 1 hour.
Advantages: Non-invasive, high sensitivity, minimal lab infrastructure needed.

3. Liquid Biopsy for Cancer Detection
Liquid biopsy detects circulating tumor DNA (ctDNA) from blood. It allows for early diagnosis, monitoring response to treatment, and detecting recurrence—especially in cancers like breast, colon, and lung.
Example: The Galleri™ test can screen for over 50 types of cancer from a single blood draw.
Clinician Tip: Use as an adjunct in high-risk individuals or those with a family history of cancer.
4. CRISPR-Based Diagnostics (e.g., SHERLOCK, DETECTR)
CRISPR isn’t just for gene editing—it now powers ultra-sensitive diagnostic platforms. These tools detect viral RNA (e.g., Dengue, SARS-CoV-2) in under 30 minutes with point-of-care potential.
Why it matters: Enables outbreak control, rapid isolation, and targeted treatment during epidemics.
5. AI-Powered Retinal Screening Tools
Deep learning tools like IDx-DR analyze retinal images to detect diabetic retinopathy, glaucoma, and macular degeneration without an ophthalmologist. These tools are already FDA-approved and used in primary care.
Best Use: Ideal for mass diabetic screening camps, community health setups.
6. mRNA Expression Tests for Sepsis and Inflammation
mRNA-based diagnostics outperform traditional CRP and procalcitonin in early sepsis detection. They differentiate bacterial from viral infections using host gene expression profiles.
Benefit: Guides timely antibiotic stewardship and reduces unnecessary prescriptions.
7. Multianalyte Cancer Screening Blood Tests
These tests evaluate patterns of DNA methylation to detect cancer before symptoms arise. Galleri and CancerSEEK are leading platforms in this domain.
Clinician Perspective: Particularly helpful for screening hard-to-detect cancers like pancreatic and ovarian.
8. Exhaled Breath Analysis for Lung Disorders
Innovative breath tests detect volatile organic compounds (VOCs) associated with asthma, COPD, and even early-stage lung cancer. These are non-invasive, fast, and suitable for outpatient settings.
Recent Research: Validated in multiple trials across Europe and Japan.
9. AI-Integrated CBC Analyzers
Next-generation hematology analyzers now include artificial intelligence algorithms that flag abnormal leukocyte morphology and detect early hematologic malignancies.
Lab Benefit: Enhances efficiency and reduces pathologist workload.
10. NIPS 2.0 – Next Generation Non-Invasive Prenatal Screening
NIPS 2.0 not only screens for trisomies (13, 18, 21) but also microdeletions, single-gene disorders, and rare chromosomal anomalies. It has near-100% sensitivity and specificity.
Recommended For: All pregnant women, especially those >35 years or with abnormal ultrasound findings.
