Although early testing can reduce long-term healthcare costs, insurers may not capture the future savings because members frequently change plans. Strom says quarterly pressures and fragmented coverage can encourage short-term decisions even when prevention would benefit the healthcare system overall.

Members often change insurers within a few years
The insurer paying for prevention may not receive the later savings
Public companies face quarterly earnings pressure
Professional recommendations do not guarantee coverage
Fragmentation blocks a uniform preventive-testing strategy

“why should I do this task if it's going to prevent a heart attack in a patient five or ten years down the line”

The Missing Study Behind Personalized Booster Decisions

Strom argues that repeated quantitative antibody testing across a population could connect antibody levels with infection, hospitalization, long COVID, and death. He stresses that current evidence does not yet justify firm personal recommendations, but the data could reveal who responds poorly to particular vaccines.

Track antibody levels repeatedly across a large population
Follow infections and clinical outcomes over time
Correlate outcomes with antibody concentration and affinity
Use the results to investigate individualized vaccine responses
Current data remain insufficient for definitive recommendations

“this is the kind of data that we need.”

Your Insurance Plan Can Decide Which Medical Test You Receive

Strom argues that insurance coverage shapes medical care more directly than many patients realize, including which laboratories and testing technologies clinicians can use. Consumers tend to compare premiums and copays during enrollment but cannot reasonably predict every future diagnostic need.

Insurers can restrict both tests and laboratories
Patients with different coverage may receive different testing technologies
Coverage limitations often become visible only after serious illness
Healthcare choices are too complex for conventional informed-consumer assumptions

“your insurance company decides what tests your doctor can order and from what laboratory.”
Charles Strom · 56:54

“the paradigm of, you know, an informed consumer in a capitalist system with free enterprise, I think doesn't work very well for healthcare.”

How Saliva Could Help Resolve Suspicious Lung Nodules

Liquid Diagnostics' open platform detected circulating tumor DNA in patients with early-stage lung cancer. Strom describes an NIH-funded study testing whether saliva, plasma, or both can help determine which indeterminate CT nodules warrant biopsy.

Most lung cancer is diagnosed after curative treatment is unlikely
Spiral CT scans often reveal nodules whose status is uncertain
The platform detected circulating tumor DNA in early-stage disease
The study aims to reduce unnecessary biopsies while identifying dangerous nodules

“he could UH detect circulating tumor DNA in patients with early stage lung cancer, something that had never been done before successfully.”
Charles Strom · 12:51

“to see if we can inform the decision about who needs a biopsy UH and who doesn't need a biopsy”

What Quantitative COVID Antibody Results Add

Unlike qualitative home tests or semi-quantitative laboratory reports, Liquid Diagnostics' saliva assay reports an antibody concentration and compares it with a vaccinated reference population. Repeated noninvasive testing can show how an individual's levels change over time.

PCR detects the virus rather than antibodies
Home antibody tests generally report only positive or negative
A concentration becomes more meaningful when paired with a population percentile
Saliva collection enables repeated longitudinal measurements

“Our test actually gives you the level of your antibody”
Charles Strom · 20:06

“Then we tell you you're in the eightieth percentile for all patients who have been vaccinated against COVID”

The Murder Case That Helped Establish Forensic DNA in Illinois

Before forensic DNA was routinely admitted in Illinois courts, prosecutors asked Strom to assist with difficult cases. In one case, DNA evidence identified a murdered woman from remains burned in a steel drum, and the evidence survived the admissibility process.

Forensic DNA was not yet routinely admitted in Illinois
Scientific evidence had to pass a Frye hearing
The victim's identity was established from severely burned remains
The DNA evidence contributed to the murder conviction

“We were able to actually to identify his wife from the charred remains in UH the steel drum.”

The Heel Stick That Can Transform a Child's Life

Strom calls newborn screening an underappreciated system for finding rare metabolic diseases before irreversible damage occurs. He describes children who avoided devastating neurological outcomes because screening led quickly to specialized diets and treatment.

California screens newborns for roughly fifty inherited metabolic disorders
Early identification connects children with specialist care
Some severe metabolic diseases can be controlled through diet
Legislative mandates also secure coverage for follow-up care

“Newborn screening is one of the most amazing phenomenon for disease identification and early treatment that nobody knows about.”

Sequencing Found a Treatable Disorder Behind a Cerebral Palsy Diagnosis

An eighteen-month-old child with hypotonia and spastic movements had been diagnosed with cerebral palsy. Whole-exome sequencing instead revealed a treatable inherited metabolic disorder, and the child began improving after targeted treatment.

The child's symptoms had been attributed to cerebral palsy
Whole-exome sequencing compared genes across the child and parents
Testing identified a specific inherited metabolic disorder
A molecular diagnosis changed treatment and prognosis

A Two-Minute Saliva Collection Instead of a Blood Draw

The saliva test uses a plastic wand with a sponge held between the cheek and gums for two minutes. Collection can occur at home or in an office, after which the sample can be mailed in appropriate biohazard packaging.

No blood draw is required
Collection takes about two minutes
Samples can be collected in multiple settings
Mail-in processing supports repeated testing
The underlying assay cost is comparable to a blood test without phlebotomy costs

“You just put plastic wand with a sponge on the end of it into your mouth between your cheek and gums for two minutes.”

Why Strom Chose Applied Science Over Basic Research

Strom distinguishes basic scientists who investigate a narrow problem deeply from applied scientists who ask how discoveries can help people. His career focused on translating laboratory knowledge into medical and forensic practice.

Basic science pursues deep understanding of a specific problem
Applied science emphasizes practical human benefit
Modern medicine calls this translational medicine
Strom used academic freedom to bring DNA testing into forensic cases

“I've always been what I call an applied scientist.”
Charles Strom · 06:47

“how are we going to take what we learned at the lab bench and put it into practice?”

Distrust the Experiment That Gives You Exactly What You Expected

Strom recalls mentor Albert Dorfman's warning that expected results deserve special skepticism. Discovery often comes from anomalies and accidents, yet modern science's project-managed structure can leave too little room for investigating the unexpected.

Expected findings may reflect confirmation bias
Unexpected observations can reveal new mechanisms
Fleming's accidental discovery of penicillin illustrates the point
Rigidly managed research can discourage anomaly-driven discovery

“when I designed an experiment and I think I know what the results should be, and I get that result, I don't trust it.”

“science and discovery is about what you're not expecting.”

Why Future Geneticists Must Understand Algorithms

As sequencing becomes routine, Strom says the core challenge is interpreting the enormous volume of resulting data. Medical professionals need enough informatics literacy to understand algorithmic strengths, weaknesses, and blind alleys rather than surrendering judgment to technical specialists.

Next-generation sequencing has reduced the relative importance of wet-lab work
Data interpretation is now a central genetics skill
Computer specialists may lack clinical context
Clinicians must recognize algorithmic assumptions and weaknesses
Large datasets can support valuable medical prediction

“you have to get a handle on the informatics.”
Charles Strom · 1:06:44

“you need to know where the weaknesses are in the computer algorithms or else you're going to start, you know, being let off on blind…”

How Reimbursement Rules Reshape Medical Practice

Strom uses Medicare diagnostic-related groups and procedure reimbursement to illustrate how policy changes alter institutional behavior, specialty power, and career economics. Even scheduling software can transform clinical work by imposing standardized appointment lengths that conflict with complex care.

Payment by diagnosis changed hospital incentives
Higher procedural reimbursement strengthened procedure-heavy specialties
Later adjustments shifted incentives toward primary care
Standardized scheduling can undermine complex specialist visits
Medical legislation frequently produces second-order effects

“one of the most important things that I've learned is unintended consequences.”
Charles Strom · 1:09:10

“be careful when you legislate anything that has to do with medicine.”
