Arlington Scientific’s serology product line delivers high-quality diagnostic test kits for accurate detection of infectious diseases and immune responses. Anchored by decades of expertise in syphilis testing, our portfolio includes RPR, VDRL, and TPHA assays.
Manufactured in the USA, ASI kits are engineered for consistency, sensitivity, and ease of interpretation, supporting reliable performance across diverse clinical laboratory workflows.

A nontreponemal test used for the screening of syphilis; a sexually transmitted disease caused by the bacterium Treponema pallidum (a spirochete bacteria).
A nontreponemal test used for the screening of syphilis; a sexually transmitted disease caused by the bacterium Treponema pallidum (a spirochete bacteria).
Sets include human serum controls—Reactive, Weak Reactive, and Nonreactive—for nontreponemal flocculation tests detecting reagin antibodies in serum.
A nontreponemal test used for the screening of syphilis. This VDRL test can also be used to detect if syphilis has involved the central nervous system (Neurosyphilis) by testing cerebral spinal fluid in clinical diagnostic settings.
ASI Synthetic VDRL Antigen is a nontreponemal test for syphilis screening. It qualitatively and semi-quantitatively detects reagin antibodies in serum and can detect neurosyphilis using CSF in clinical diagnostic settings.
Used as a confirmatory syphilis test. A convenient qualitative and semiquantitative microhemagglutination assay detecting IgG and IgM antibodies to Treponema pallidum in human serum and EDTA plasma.
Microparticulate carbon RPR antigen improves visual distinction between reactive and nonreactive results. Flocculation forms aggregates (reactive); smooth gray or a central button indicates nonreactive.
A convenient and specific rapid latex particle agglutination test for the qualitative and semiquantitative determination of rubella virus antibodies in serum. Aids in diagnosing recent or active infection and immune status.
Infectious mononucleosis is a contagious disease most commonly caused by Epstein-Barr virus (EBV). This color-enhanced test detects heterophil antibodies associated with IM in human serum or EDTA plasma.
A convenient and specific slide agglutination assay for the qualitative detection of coagulase (both clumping factor and protein A) to identify Staphylococcus aureus to the exclusion of other species of staphylococci.
A rapid, color enhanced latex agglutination test to detect clumping factor and/or Protein-A, characteristics associated with Staphylococcus aureus colonies obtained from culture. Color enhanced for visual reading.
Systemic Lupus Erythematosus (SLE) is an autoimmune disorder. This is a specific latex slide agglutination assay for the detection of anti-deoxyribonucleoprotein (anti-DNP) in human serum for clinical diagnostic use.
RF is a chronic inflammatory autoimmune disorder causing pain and disability. This slide agglutination assay qualitatively and semiquantitatively determines Rheumatoid Factor (RF) in human serum.
A specific test used as an aid in the qualitative detection of hemoglobin S (Hb-S) in anticoagulated whole blood. The test does not distinguish between sickle cell disease (HbS/S) and sickle cell trait (HbS/A) in screening.
A specific latex slide agglutination assay for the qualitative and semiquantitative detection of Antistreptolysin-O (ASO) antibodies in human serum. No initial dilution of patient sample is required for this test.
C-Reactive Protein (CRP) is a protein produced by the liver in response to acute injury, infection, or inflammation. Detects C-Reactive Protein (CRP) in human serum. No initial dilution of patient sample is required for this test.
A wide range of bulk latex serology reagents ready for small to large companies seeking to enhance their current product or develop new product lines. Exported globally.
