Collection Decision Guide
How to Choose the Right Collection Type for Your Test
Choosing the right specimen collection method is critical to accurate diagnostic results. This guide helps you understand which collection type works best for your specific testing needs, ensuring sample stability, patient compliance, and reliable outcomes.

When to Choose Blood Collection
Blood collection remains the gold standard for diagnostic accuracy. Choose venipuncture or capillary blood collection when your test requires:
Ideal Use Cases
- Hormone precision testing (estradiol, cortisol, thyroid panels)
- Oncology markers (MRD, circulating tumor DNA, ctDNA)
- Metabolic panels (lipids, glucose, insulin, HbA1c)
- Toxicology confirmation testing
- Complete blood counts and chemistry panels
Why Blood Works Best
Blood provides the most accurate quantitative measurement of biomarkers. For oncology and MRD testing, specialized cfDNA tubes like Streck Cell-Free DNA BCT preserve circulating tumor DNA for up to 14 days, ensuring sample integrity during transport.
Recommended Components
- Streck cfDNA tubes (oncology/MRD)
- BD Vacutainer (clinical chemistry)
- Tasso+ or Mitra VAMS (at-home capillary collection)

When to Choose Urine Collection
Urine collection offers a non-invasive option ideal for infectious disease testing and toxicology screening. Choose urine when:
Ideal Use Cases
- STI testing (Chlamydia, Gonorrhea, Trichomonas)
- UTI detection and culture
- Drug screening and toxicology
- Kidney function markers
Why Urine Works Best
Urine is completely non-invasive and ideal for pathogen capture. Modern PCR-compatible urine devices protect nucleic acids during transport, ensuring accurate molecular testing results.
Recommended Components
- Roche PCR Urine Collection Device
- Copan UriSwab
- Zymo Urine DNA/RNA Shield
- RDI Peetainer
- Standard sterile urine cups with temperature strips

When to Choose Saliva Collection
Saliva offers the easiest self-collection experience with excellent DNA stability. Choose saliva when:
Ideal Use Cases
- Pharmacogenomics (PGx) testing
- Genetic carrier screening
- Ancestry and hereditary testing
- Hormone monitoring (cortisol, testosterone)
- Wellness and consumer health panels
Why Saliva Works Best
Saliva collection requires no needles, no medical training, and provides high-quality DNA yields. Modern stabilization buffers keep samples stable at room temperature for weeks, making it perfect for mail-in testing programs.
Recommended Components
- DNA Genotek Oragene (OGD-500, OGD-510)
- DNA Genotek OMNIgene ORAL
- Zymo Saliva DNA/RNA Shield

When to Choose Buccal/Swab Collection
Swab collection captures pathogens directly from the infection site for maximum sensitivity. Choose swabs when:
Ideal Use Cases
- STI swab tests (vaginal, cervical, rectal, throat)
- HPV self-collection
- Respiratory pathogens (flu, RSV, COVID-19)
- Wound and skin infections
- Microbiome niche sampling
Why Swabs Work Best
Swabs capture pathogens directly at the source, improving test sensitivity. Flocked swab technology (like HydraFlock and FLOQSwabs) releases more sample material than traditional fiber swabs, enhancing detection rates.
Recommended Components
- Puritan HydraFlock NP/OP swabs
- Copan FLOQSwabs and UltraFLOQ
- DNA Genotek OCD-100 (vaginal microbiome)
- Copan ESwab (general purpose)

When to Choose Stool/Fecal Collection
Stool collection is essential for gut health analysis and GI pathogen detection. Choose stool when:
Ideal Use Cases
- Microbiome sequencing and analysis
- GI pathogen panels (C. diff, Salmonella, E. coli)
- H. pylori detection
- Inflammatory markers (calprotectin)
- Fecal occult blood testing (FOBT)
- Parasitology testing
Why Stool Works Best
Stool samples reveal gut flora balance and GI infections better than any other specimen type. DNA stabilization technology preserves microbial DNA during shipping, enabling accurate microbiome profiling.
Recommended Components
- DNA Genotek OMNIgene GUT
- Zymo DNA/RNA Shield Fecal Collection
- Copan FecalSwab
- Cary-Blair transport media
- Protocult collection devices

When to Choose At-Home Blood Collection
Blood collection is essential for gut health analysis and GI pathogen detection. Choose stool when:
Ideal Use Cases
- Consumer wellness programs
- Telehealth diagnostic panels
- Hormone follow-up testing
- Food sensitivity panels
- GLP-1 monitoring for weight loss programs
- Chronic disease management
- Clinical trial remote sampling
Why At-Home Blood Works Best
Devices like Tasso+ and Mitra VAMS allow patients to self-collect capillary blood without needles or lancets. Dried blood spot (DBS) technology keeps samples stable at room temperature, simplifying logistics and expanding your market to direct-to-consumer programs.
Recommended Components
- Tasso+ (push-button capillary collection)
- Neoteryx Mitra VAMS (volumetric absorptive microsampling)
- DBS Cards (ADX-100, Eastern Business Forms)
