DNA Profile Verification Test

The DNA Detection Test is designed to determine whether usable human DNA is present on a submitted item before proceeding with forensic relationship testing. This screening test is strongly recommended when submitting non-standard or forensic samples to ensure that sufficient DNA is available for accurate analysis.

If you are planning to use personal items or trace evidence for a forensic paternity, sibling, grandparent, or avuncular DNA test, this detection test helps reduce the risk of inconclusive results due to insufficient DNA.

Why Order a DNA Detection Test First?

Forensic and non-standard samples may not always contain enough recoverable DNA for full relationship testing. This test helps:

• Confirm the presence of human DNA on an item

• Determine whether a sample is suitable for forensic DNA analysis

• Reduce the likelihood of inconclusive or failed forensic testing

• Save time and additional testing costs

This step is especially important when submitting items such as toothbrushes, razors, hair with root, or other personal effects.

When Should You Use a DNA Detection Test?

You should consider this test when:

• Submitting non-standard or trace DNA samples

• Using personal items for forensic relationship testing

• Unsure whether an item contains viable human DNA

• Seeking to verify DNA presence before ordering a forensic DNA comparison

Accepted Sample Types

This test is commonly performed on:

• Clothing

• Used drinking glasses

• Hair with root

• Nail clippings

• Personal items suspected to contain biological material

Items Not Accepted

The following items are not eligible for DNA detection testing, or may need approval prior to any testing:

• Items containing fecal matter, such as soiled diapers

• Teeth, whether extracted or naturally fallen

• Bone samples

• Fetal demise samples

• Paraffin-embedded tissue blocks

• Muscle or organ tissue

If you are unsure whether your item qualifies, it is recommended to confirm eligibility before submitting a sample.

Laboratory Analysis

All testing is performed at an accredited laboratory using validated DNA extraction methods designed to detect and evaluate the presence of human DNA in forensic samples.

Turnaround Time

Results are typically available within 5 to 7 business days after the laboratory receives the item.

Important Information

• This test only determines whether human DNA is present

• It does not compare DNA or establish a biological relationship

• A separate forensic relationship test is required for paternity or kinship analysis

• Processing times may vary depending on sample condition
