I did the job before I advised on it.

Today

I consult independently through my own firm, Ebihara Solutions, mostly remotely from Japan, with a home in Stockholm. The laboratories I know best are Swedish. The work is offered to laboratories in Sweden, the rest of Europe and the Asia-Pacific: workflow reviews, LIMS requirements, automation, method validation, quality systems and commissioning, with site visits where the work needs them and a longer on-site engagement open for the right project. Site visits in Swedish, English or Japanese; written work in Swedish or English.

Miguel Barroso has extraordinary working abilities, namely his intelligence, positive attitude and engagement. He can multi-task very well and is always ready to lend a hand whenever needed. His communication skills add on top, turning him an asset to any company/service. Here at Clinical Pharmacology in Karolinska Hospital, his contributions are recognized by everyone and the workflow is much smoother due to him.

Professional license and degrees

In Sweden, biomedicinsk analytiker is a protected professional title and a licensed profession. The license is issued by Socialstyrelsen, the National Board of Health and Welfare, and recorded in its HOSP register of licensed health and medical care personnel, where status can be confirmed. Ask and I will give you what the register needs to look me up.

• License

  Legitimerad biomedicinsk analytiker, effective 15 September 2010, issued by Socialstyrelsen.

• Degree

  Biomedicinsk analytikerexamen, Degree of Bachelor of Science in Biomedical Laboratory Science, 180 credits, Karolinska Institutet, 2010. The professional degree that carries the license.

• Degree

  Medicine kandidatexamen, Bachelor of Medical Science with a major in Biomedical Laboratory Science, 180 credits, Karolinska Institutet, 2010. The same program confers both. Degree project graded väl godkänd.

Employment

1. 2021 – 2024

   Chief Laboratory Technician, Toxicology

   ABC Labs AB, Stockholm

   Stood up a new business line, drugs of abuse and other biomarkers by LC-MS/MS with the clinical chemistry that checks specimen authenticity beside it, in a company that had until then been a pandemic testing operation. My remit ran from reference material procurement through LIMS design and method validation to customer contact and reporting to finance.

   I ran the technical side of the toxicology unit’s accreditation, the validation framework, audit preparation, CAPA and documentation, with the QA function alongside. I started in November 2021 and the accreditation was granted in October 2023: medical testing to ISO 15189 and workplace drug testing to EWDTS, on the public register as Swedac 10532. Accreditation is won by the laboratory and QA together. I led a team of eight technicians and engineers. The build is set out on the selected work page.

2. 2018 –

   Owner

   Ebihara Solutions, sole trader (enskild firma)

   Registered in 2018 and run alongside full-time employment; the first customer was the hospital I worked in. It designs, makes and delivers laboratory parts that no vendor sells, and since 2024 it is the firm I consult through.

   Traded with customers between 2018 and 2024: 234 tube inserts to Clinicon AB across two orders in 2021 and 2022, and 200 parts to clinical chemistry at Skåne University Hospital in Lund in 2018, among others. Small numbers, real customers, signed for on delivery.

3. 2016

   Application Specialist

   Hamilton Nordic AB, Kista

   The vendor’s side of the robots I had been running: independent planning and programming of Hamilton STAR platforms, customer support across the Nordics, on-site service, and following up application requirement specifications against what the laboratory needed. It is why I can say what a vendor’s installation qualification does and does not prove. I then returned to Karolinska.

4. 2010 – 2021

   Biomedical Scientist

   Karolinska University Hospital, Clinical Pharmacology, Huddinge

   Eleven years of routine and development in therapeutic drug monitoring and drugs-of-abuse analysis by LC-MS/MS, with clinical chemistry and PCR alongside. The drugs-of-abuse laboratory held accreditation from the College of American Pathologists alongside the department’s Swedac accreditation to ISO 15189 and ISO/IEC 17025, so the routine I ran answered to the US checklist and the ISO standards at the same time. Instrument responsibility for the department’s automation platforms, and from 2015 the main programmer of its Hamilton STAR liquid handlers. I kept my access to the doping control laboratory throughout and helped with its projects, so I worked across all three of the department’s laboratories.

   Method development, student supervision in routine teaching sessions with the instructional material to go with it, and two blood-sampling instructional films for the hospital. Interrupted by the 2016 stint at Hamilton.

5. 2009 – 2010

   Laboratory Assistant

   Karolinska University Hospital, Swedish Doping Control Laboratory, Clinical Pharmacology, Huddinge

   Summer work over two summers while still studying, running doping analyses independently in a laboratory accredited under the World Anti-Doping Agency. A student job, before the license in September 2010, in the same department I then spent eleven years in.

Publications

Three peer-reviewed papers in dried blood spot analysis, first author on one. The years are publication years: the hematocrit paper rests on bench work at Karolinska and was published after I had left; the drugs-of-abuse and phosphatidylethanol methods were developed while ABC Labs’ toxicology laboratory was being built, and the PEth method was the first one that laboratory took into routine.

Conference posters

Work from the Karolinska years was presented as posters at three congresses of the International Association of Therapeutic Drug Monitoring and Clinical Toxicology. Rotterdam in 2015 carried an automated plasma multi-method for antipsychotics and an antidepressant; Kyoto in 2017 the whole-blood flow, Automated sample preparation of whole blood — the need for speed, which is the flow on the selected work page and which I am first author on; Iguazu in 2019 the hematocrit-in-dried-blood-spots work that became the paper above.

Peer review

Two completed reviews for the Journal of Pharmaceutical and Biomedical Analysis in 2026, recorded on my ORCID profile by Elsevier. My name appears in the literature in four spellings, one of them a misspelling under correction; ORCID 0000-0003-2518-3176 is the reliable index.

How I got here

I live in Japan and keep a home in Stockholm. Japanese is the reason I could move here; the year in Kyoto came between the hospital years, not instead of them.

The design work started because the parts I wanted did not exist. I took a 3D CAD course at Dalarna University in 2018, the same year the first tube inserts went out of the door, and the laboratory that bought them was the one I worked in. It grew from there into something small but real, and it is still the part of the work I enjoy most.
