• Medical laboratory technology
• Respiratory therapy
• Diagnostic imaging and radiologic technology
• Physical therapy assisting
• Occupational therapy assisting
• Surgical technology
• Health information management
• Forensic science and toxicology
• Clinical nutrition and dietetics
• Emergency medical services

The beauty of an allied science degree is its flexibility. Some programs are designed as direct pipelines to licensure and employment, while others serve as stepping stones to advanced degrees and specialized careers. According to the Bureau of Labor Statistics (bls.gov), employment in healthcare occupations is projected to grow much faster than the average for all occupations, adding about 1.8 million new jobs over the 2022–2032 decade — and allied health professionals make up a significant portion of that growth.

Allied Health Occupations: A World of Possibilities

One of the things I love about working in this space is watching job seekers discover just how many allied health occupations exist. Most people can name a few — maybe physical therapist or X-ray technician — but the full spectrum is genuinely impressive. The Association of Schools Advancing Health Professions recognizes over 80 distinct allied health professions, each with its own educational pathway, credentialing requirements, and career trajectory.

Forensic Toxicology: Where Allied Science Meets Criminal Justice

One of the most intriguing career paths that an allied science degree can lead to is forensic toxicology. I regularly get questions from job seekers who are fascinated by forensic science but aren't sure how to break into the field. Let me break down the forensic toxicology job description so you can decide if it's right for you.

Forensic Toxicology Job Description

A forensic toxicologist is a scientist who analyzes biological samples — blood, urine, hair, tissue, and other specimens — to detect and quantify the presence of drugs, alcohol, poisons, and other toxic substances. Their work plays a critical role in criminal investigations, workplace drug testing programs, medicolegal death investigations, and human performance evaluations (such as DUI cases).

Here's what a typical forensic toxicology job description includes:

• Collecting, preserving, and processing biological specimens following strict chain-of-custody protocols
• Performing qualitative and quantitative analyses using advanced instrumentation such as gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS)
• Interpreting analytical results in the context of pharmacology, pharmacokinetics, and case circumstances
• Preparing detailed written reports of findings
• Providing expert testimony in court proceedings
• Maintaining quality assurance and quality control procedures
• Staying current with emerging drugs of abuse, analytical methods, and regulatory requirements

Education and Credentials for Forensic Toxicology

While an allied science degree at the associate level provides a strong scientific foundation, most forensic toxicology positions require at minimum a bachelor's degree in forensic science, toxicology, chemistry, biochemistry, or a related allied science field. Many employers and medical examiner offices prefer candidates with a master's degree or doctoral degree.

Professional certification through the American Board of Forensic Toxicology (ABFT) is highly valued and often required for advanced positions. The National Institutes of Health (nih.gov) also provides extensive research resources on toxicology that many professionals reference throughout their careers.

Salary and Job Outlook for Forensic Toxicologists

According to the Bureau of Labor Statistics, forensic science technicians — the broader category that includes forensic toxicologists — earn a median annual salary of approximately $63,740, with the top 10% earning over $103,000. Job growth for forensic science technicians is projected at 14% from 2022 to 2032, which is much faster than average.

Keep in mind that forensic toxicologists working in larger metropolitan areas, at federal agencies, or in private consulting typically earn at the higher end of this spectrum. Those with doctoral degrees and board certification can command significantly higher salaries.

Choosing the Right Allied Science Degree Program

Not all allied science degree programs are created equal, and I've seen too many students make choices they regret. Here's my advice for selecting a program that will genuinely serve your career goals:

Accreditation Matters — A Lot

Always verify that your program is accredited by the appropriate body. For allied health programs, this typically means accreditation from the Commission on Accreditation of Allied Health Education Programs (CAAHEP) or a discipline-specific accreditor. Without proper accreditation, you may not be eligible to sit for certification exams, which can effectively lock you out of the profession.

Associate vs. Bachelor's Degree

For many allied health occupations, an associate-level allied science degree is sufficient for entry-level employment. Roles like medical laboratory technician, respiratory therapy, radiologic technology, and surgical technology can all be entered with a two-year degree. However, there's a growing trend toward requiring bachelor's degrees, and having a four-year degree opens doors to supervisory roles, higher pay, and specialized positions like forensic toxicology.

My recommendation: if you can invest in a bachelor's degree, do it. The return on investment is significant over a 30-year career. If time or finances make that difficult right now, start with an associate degree and choose a program with clear articulation agreements for bachelor's completion.

Clinical Experience and Internships

The best allied science degree programs include substantial hands-on clinical rotations or internship components. This practical experience is invaluable for building skills, making professional connections, and strengthening your resume. When I review job postings on healthcareers.app, I consistently see employers prioritize candidates with clinical experience over those with classroom-only education.

Career Advancement with an Allied Science Degree

One of the most common concerns I hear from prospective students is whether an allied health career offers room for growth. The short answer: absolutely.

Here are proven pathways for career advancement in allied health:

1. Specialization: Many allied health fields have subspecialties that command higher salaries. A radiologic technologist might specialize in MRI, CT, or mammography. A medical laboratory scientist might focus on molecular diagnostics or blood banking.
2. Leadership and Management: With experience and often a bachelor's or master's degree, allied health professionals move into supervisory, management, and director-level positions.
3. Education: Teaching the next generation of allied health professionals is a rewarding path, typically requiring a master's degree or higher.
4. Advanced Practice: Some fields, like physical therapy, have evolved to require doctoral-level education, but an allied science degree at the bachelor's level provides the prerequisite foundation.
5. Cross-Disciplinary Roles: Allied health professionals frequently transition into health informatics, quality improvement, healthcare administration, regulatory affairs, or consulting.

The Job Market for Allied Health Professionals in 2024 and Beyond

I want to be honest with you about the current job market because I think transparency builds trust. The outlook for allied health occupations is overwhelmingly positive, but it's not uniformly so across every specialty and geography.

The factors driving demand include:

• An aging population: As baby boomers continue to age, the need for diagnostic services, rehabilitation, respiratory care, and other allied health services grows substantially.
• Healthcare access expansion: More insured Americans means more demand for healthcare services at every level.
• Technology advancement: New diagnostic tools, imaging modalities, and laboratory techniques create entirely new roles and expand existing ones.
• Workforce shortages: Many allied health fields face significant workforce shortages, which translates to strong bargaining power for credentialed professionals.

According to data from the Centers for Disease Control and Prevention (cdc.gov), chronic disease prevalence continues to rise in the United States, which directly drives demand for the diagnostic, therapeutic, and rehabilitative services that allied health professionals provide.
