Pathway to Become a Clinical Laboratory Scientist
What does a CLS do?
Clinical Laboratory Scientists work in laboratories of hospitals and other health
organizations. They are responsible for performing tests related to the examination
and treatment of patients, helping physicians to diagnosis and treat disease.
Using sophisticated instrumentation, technology, and highly skilled manual
techniques, Clinical Laboratory Scientists:
Examine and analyze body fluids, tissues and cells
Identify infective microorganisms
Identify blood-clotting abnormalities
Cross-match donor blood for transfusions
Test blood for drug levels to measure the efficacy of particular treatments
Evaluate test results for accuracy and help interpret them for the physician
Careers in the field of Clinical Laboratory Science are open to those who have an
interest in medical science. It is great for those who have an interest in the medical
field, but may not desire to be hands-on with patients. Students who enter this
profession should have an affinity for math and for chemical and biological sciences.
Where do I start?
The first step is to acquire a Bachelor Degree, including courses specific to
academic requirements of the State of California Public Health Department:
16 semester or equivalent quarter units of chemistry, which must include
clinica
l chemistry OR analytical and biochemistry.
18 semester or equivalent quarter units of biology, which must include
hematol
ogy, immunology, and medical microbiology.
3 semester or equivalent quarter units of physics (light and electricity).
Local, unaffiliated schools with course programs that prepare students for a career
in Clinic
al Laboratory Science:

After you have acquired a Bachelor degree with the above requirements, the next
step is to apply for a CLS Generalist training license through the California
Department of Public Health Laboratory Field Services. Visit the LFS website to
create an account and submit an application. You will need to send your official
transcripts sent to LFS (instructions are included on the website).

Once you receive your training license, you are ready to apply for a training
program/i
nternship. Internships last 52 weeks, as required by the State of California.
There are more than 800 approved schools of medical technology, which are located
primarily in hospitals. Some schools provide the option of earning education with
your internship included (see: Loma Linda University), and some schools offer
internship as part of your four-year degree. Alternatively, there are independent
training programs which are not affiliated with any university, giving you the freedom
to complete your degree requirements at a school of your choice.

Independent Training Programs
Independent training programs are great for anyone who obtained their degree at a
school that is not affiliated with a training hospital. These programs typically include
a stipend, and take a limited number of students per year. Luckily, the central valley
has several CLS training programs to choose from:

Affiliated Internships
Affiliated internships are programs that allow you to complete your internship
through your school and/or hospitals that are exclusively affiliated with that school,
which can make getting an internship easier. Some examples:
University of California Irvine:
52 week NAACLS accredited training program
Students are eligible to take the external exam leading to licensure as a
California CLS and certification as a Medical Laboratory Scientist by the
American Society for Clinical Pathology. There are no tuition fees. A
scholarship is provided to admitted students, paid on a monthly basis; amount
is dependent on annual budget. Program takes 6 students per year.

University of California Davis:
52 week training program
The applicant must have a B.A. or B.S. degree and must be qualified to be
issued a CLS training license by CDPH prior to the start of training. There are
no tuition fees. There is a stipend that is variable and not guaranteed. Program
takes 8-12 students per year.

San Francisco State University: 56 week NAACLS accredited training program
The CLS p
rogram consists of a 16-week semester of didactic and laboratory
work and a 40-week off-campus internship at affiliated clinical laboratory sites.
Program takes 29-59 students per year.

San Jose State University: 52 week training program
The Clin
ical Laboratory Scientist Training Program at San Jose State
University is a 12 month post-baccalaureate training program that prepares
students to take the ASCP national exam for Clinical Laboratory Scientists.
Students spend 32 hours training at a clinical site and 8 hours a week in lecture
with no breaks in the training year. Program takes approximately 25 students
per year.

Loma Linda University: 2 year NAACLS accredited program
LLU offers a professional bachelors program. The freshman and sophomore
years are taken at any accredited college or university. Entry to the program is
at the junior-year level. After completion of the program, the student is
awarded a Bachelor of Science degree and is eligible for state licensure and to
take the national board examination. Program takes 18-21 students per year.

Getting Your License
After you complete your internship you are ready to take the exam to become a
licensed Clinical Laboratory Scientist. Your training institution will submit the
appropriate forms to the California Department of Public Health. You will need to
register with ASCP and apply to take your exam for your CLS license; this can be
done up to 2 weeks prior to completion of your internship.
After passing the exam, you can apply for a CLS license with CDPH. You will need to
upload a
certificate of training completion and letter of training verification (from
your training facility), and verification of completion of exam.
Last but not least, applicants are required to take a tutorial and pass a quiz on
Califor
nia State laboratory law:

Lab Field Services will review your documents and issue a California CLS license.
Career Outlook
According to the Bureau of Labor and Statistics, the projected job growth for the
CLS career is higher than average, at 13% between 2016 and 2026 (BLS.gov). The
American Society for Clinical Pathology’s 2017 wage survey of medical laboratories
places California CLS at the highest paid, with an average hourly wage of $48.70;
Connecticut follows in second place at $34.69. ASCP lists the average annual salary
for CLS as $61,112.31. The percent change in salary between 2013, 2015, and 2017
was an increase of 2.15% for CLS in states surveyed
(https://academic.oup.com/ajcp/advance-article/doi/10.1093/ajcp/aqy139/5112880).
