What are the best point-of-care diagnostic devices for bedside testing in urgent care and clinic settings?

The “best” point-of-care (POC) diagnostic device depends on what you need to test and the volume/speed/space of your urgent care or clinic. In practice, the best bedside devices are usually the ones that are:

• Fast: result in minutes
• Accurate: good sensitivity/specificity
• Easy to use: minimal training, few steps
• Connected: can send results to the EMR/LIS
• Low-maintenance: simple QC, low downtime
• Clinically useful: actually changes management

Best-in-class POC devices by common use case

1) Respiratory infections

Best options:

• Cepheid GeneXpert Xpress
• Roche cobas Liat
• Abbott ID NOW (especially for rapid molecular testing)

Why they’re strong:
These are among the most useful bedside/near-patient molecular platforms for COVID-19, influenza, RSV, and other respiratory pathogens. They’re typically much more accurate than antigen tests and much faster than central lab PCR.

Best for: urgent care, walk-in clinics, seasonal respiratory testing, treatment decisions at the visit.

---

2) Strep testing

Best options:

• Abbott ID NOW Strep A
• Cepheid Xpert Xpress Strep A
• High-quality rapid antigen strep devices when molecular isn’t needed

Why they’re strong:
Molecular strep tests generally outperform older antigen tests and reduce missed cases.

---

3) Cardiac biomarkers

Best options:

• Abbott i-STAT
• Roche cobas h 232 or similar troponin-capable POC systems depending on region
• Siemens epoc in some settings

Why they’re strong:
Useful for troponin, BNP/NT-proBNP in some platforms, and sometimes basic chemistry/electrolytes alongside clinical assessment.

Best for: chest pain evaluation in settings where rapid triage is needed, though many clinics still send true ACS workups to EDs.

---

4) Basic chemistry / blood gases / electrolytes

Best options:

• Abbott i-STAT Alinity
• Siemens epoc
• Radiometer ABL platforms

Why they’re strong:
These give fast electrolytes, creatinine, blood gases, lactate, glucose, and related parameters. Very useful for urgent decision-making.

Best for: dehydration, renal issues, DKA evaluation support, sepsis screening, asthma/COPD exacerbation, procedural clinics.

---

5) Glucose and ketones

Best options:

• Standard glucometers from major vendors
• β-hydroxybutyrate ketone meters for DKA risk assessment

Why they’re strong:
Cheap, fast, reliable, and essential in almost every clinic.

---

6) Urinalysis

Best options:

• Siemens Clinitek
• Roche Urisys
• WITNESS/strip readers depending on workflow

Why they’re strong:
Automated urinalysis readers improve consistency over visual dipsticks and are good for UTI screening, hematuria, proteinuria, and pregnancy-related workflows.

---

7) Hematology / CBC

Best options:

• Abbott Alinity h-series POC solutions in some environments
• HemoCue WBC / Hb systems
• Select compact analyzers from Sysmex or Nihon Kohden depending on region and budget

Why they’re strong:
For full CBC needs, POC options vary by geography and regulatory setting. Hemoglobin-only devices are excellent for anemia screening or peri-procedural checks.

---

8) Coagulation

Best options:

• CoaguChek for INR
• Hemochron systems in higher-acuity settings

Why they’re strong:
Very useful for warfarin monitoring and some procedural workflows.

---

9) Pregnancy testing

Best options:

• Major rapid hCG tests from trusted vendors
• Automated readers if you want better documentation and fewer subjective reads

---

10) Infectious disease screening

Best options:

• OraQuick and similar rapid tests for certain infections
• Molecular platforms when you need higher sensitivity

Common uses: HIV, hepatitis, syphilis screening depending on clinic mission and regulatory approval.

How to choose the right one

Consider:

• Test menu: Do you need respiratory PCR, troponin, electrolytes, UA, INR?
• Turnaround time: 2–15 min vs 30–60 min
• Volume: low-volume clinic vs busy urgent care
• Connectivity: EMR/LIS integration
• Staff training: how many steps and how much QC
• Reimbursement/cost: instrument cost, consumables, maintenance
• Regulatory status: CLIA-waived / local approvals
• Space and portability: benchtop vs handheld
• Clinical need: will results change treatment today?

---

Practical recommendation by setting

Small clinic

• Glucose meter
• Urinalysis reader
• Pregnancy test
• Coag meter if anticoagulation patients are common
• Add ID NOW or Liat if rapid molecular testing is needed

Busy urgent care

• GeneXpert Xpress or cobas Liat
• i-STAT or epoc
• Urinalysis analyzer
• INR if needed
• CBC/hemoglobin testing if your workflow supports it

Higher-acuity outpatient clinic

• Molecular respiratory platform
• Chemistry/electrolytes/creatinine platform
• INR
• UA
• Hemoglobin/CBC support depending on patient population

Bottom line

If I had to pick the most useful “best” POC devices for bedside testing in urgent care and clinic settings, I’d prioritize:

• GeneXpert Xpress or cobas Liat for rapid molecular diagnostics
• Abbott i-STAT Alinity or Siemens epoc for chemistry/electrolytes/ABG-type testing
• CoaguChek for INR
• Siemens Clinitek for urinalysis
• HemoCue for hemoglobin screening
