IMHA, NETs, and the Clotting Risk: The DNA Connection
Immune-Mediated Hemolytic Anemia is a thrombotic disease. We explain how 'DNA webs' (NETs) released by neutrophils fuel the fire and trigger clots.

Trauma and Ischemia: Quantifying the 'Hit'
From hit-by-cars to GDVs, necrosis releases massive amounts of DNA. How cfDNA correlates with the 'Injury Severity Score' and helps triage the multi-trauma patient.

The 'Cooler' Fallacy: Why You Can't Mail EDTA Tubes on the Weekend
Putting a blood tube in a styrofoam box with an ice pack is not 'preservation.' It is a recipe for lysis. We explain the thermodynamics of shipping failure.

Sepsis vs. SIRS: Can DNA Tell the Difference?
Inflammation looks a lot like infection on a blood panel. We explore why cfDNA rises in both, and how it helps quantify the 'cytokine storm'.

Myths and Misconceptions: What cfDNA Cannot Do
A negative test doesn't guarantee health, and a positive test doesn't always mean cancer. We debunk the binary thinking that leads to clinical errors.

Beyond Cancer: cfDNA as a 'Severity Meter' in the ICU
In the Emergency Room, we aren't looking for mutations. We are looking for the total burden of cell death. How to use cfDNA to quantify exactly how hard the patient has been hit.

Tissue of Origin: The Holy Grail of Veterinary Liquid Biopsy
We can find cancer in the blood, but can we tell you where it is? We explore the current limits of localization and the future promise of methylation panels.

Lipemia: The Optical Illusion That Breaks Assays
Fat in the blood doesn't just look bad; it scatters light and clogs filters. How lipemia distorts cfDNA values and how to handle the 'milky' sample.

Freeze-Thaw Cycles: How to Shatter a Molecule
Ice crystals are sharp. We explain why refreezing a plasma sample shears long DNA fragments and ruins 'integrity index' diagnostics.

The 4-Hour Rule: The Biology Behind the Clock
Why do samples degrade after 4 hours? It's not just 'aging'—it's a biological cascade of glucose depletion and white blood cell suicide.

Nucleosomes vs. cfDNA: Same Biological Event, Different Diagnostic Signal
DNA doesn't float naked in the blood—it is wrapped around histone spools called nucleosomes. We explain why measuring the 'spool' might sometimes be better than measuring the 'thread'.

Apoptosis, Necrosis, and NETosis: The Three Engines of Cell-Free DNA
Not all DNA in the blood is the same. We break down the three biological mechanisms that release DNA—programmed death, traumatic injury, and immune defense—and what they tell us about a patient's disease.

Fragmentomics: Why Size Matters in Cancer Detection
It’s not just how much DNA is in the blood, but how long the pieces are. Learn how 'fragmentomics' allows us to spot cancer even when total DNA levels are normal.
