The Sierra Cassette test is a rapid, qualitative sandwich dye conjugate immunoassay with the physical appearance of a white plastic card or cassette. Add urine or serum sample and an accurate, visually determined result appears in just minutes. Disposable and inexpensive, the Sierra Cassette test is an effective alternative to conventional, labor intensive laboratory testing techniques.

Each Sierra Cassette device is packaged with a transfer pipette and desiccant packet under low humidity conditions in an opaque, airtight, foil pouch. Most Sierra Cassette tests have a shelf life of eighteen months and may be stored at room temperature (2-28 C).

NOTE: Refer to individual test instructions for specific timing and result interpretation. Additional liquid reagents are included with certain kits and may require refrigeration.

Sierra Cassette

The Sierra Cassette is an extension of the Sierra Cassette design with multiple analyte testing capabilities. Designed primarily for drugs of abuse screening, two uniquely coded test zones produce two independent qualitative results from a single patient sample.

QuickPac IV cassette

The Sierra Cassette Whole Blood Test incorporates new multilayer filtration and sandwich immunoassay systems in a single module, allowing both the pretreatment of whole blood sample and the immunochromatographic detection assay to be performed in one step. Just add 1 drop of whole blood to the sample well on the cassette, place buffer in the buffer well, wait ten minutes and read results.

NOTE: Refer to individual test instructions for specific timing and result interpretation. Additional liquid reagents are included with certain kits and may require refrigeration.

Sierra Strip dipstick

The Sierra Strip dipstick is a compact alternative to the Sierra Cassette. It is reliable, accurate and includes a built-in performance control. Dip the device directly into a specimen sample and a result appears within minutes.

Each Sierra Strip test is packaged under low humidity conditions in an airtight foil pouch. Most Sierra Strip tests have a shelf life of eighteen months and may be stored at room temperature (2-28 C).

NOTE: Refer to individual test instructions for specific timing and result interpretation. Additional liquid reagents are included with certain kits and may require refrigeration.

Sierra Strip dipstick

The Sierra Strip dipstick like the Sierra Cassette Whole Blood Test incorporates new multilayer filtration and sandwich immunoassay systems in a single module, allowing both the pretreatment of whole blood sample and the immunochromatographic detection assay to be performed in one step. Just add 1 drop of whole blood to the sample well on the test strip, place strip in extraction cup with buffer, wait five minutes and read results.

NOTE: Refer to individual test instructions for specific timing and result interpretation. Additional liquid reagents are included with certain kits and may require refrigeration.

Midstream

The midstream test represents the latest one-step qualitative test technology. Simply hold the tip of the device directly in the urine stream and read the result a few minutes later. No collection cups are necessary and droppers are eliminated. Primarily used for pregnancy testing, the midstream test is rapidly becoming the most popular over-the-counter test kit.

Each test is packaged in a foil pouch under controlled, low humidity conditions. All devices have a shelf life of eighteen months at room temperature (2-28 C).

NOTE: Refer to individual test instructions for specific timing and result interpretation.

Microwell EIA (ELISA)

The Microwell enzyme immunoassay (EIA) gives qualitative, semi-quantitative, or quantitative results. It is designed for laboratory use and is ideal for testing large quantities of sample specimens while keeping the per-test-cost to a minimum.

In test procedures, sample specimen is allowed to react simultaneously with antibody enzyme conjugate and antibodies immobilized on the solid phase of the well. Unbound enzyme conjugate is removed by tap water rinse and then incubated with special substrate solutions. Qualitative results are visually read by comparing the color intensity with a calibratedreference. Quantitative results are determined using an optical density well reader (also available through Sierra). Test kit ingredients and procedures vary.

Microwell EIA kits have a shelf life of approximately twelve months and require refrigerated storage (2-8 C).

Membrane EIA

The membrane immunoassay test is a solid phase immunosorbent assay that yields qualitative results using antibody-enzyme or antibody-dye conjugates. The technology is widely accepted throughout the world and well known to be reliable and consistent. It is well suited for laboratory testing and outpatient physician care.

In the test procedure, suspect treated antigen in urine or serum is transferred to a reaction pack. Substrate reagent is added immediately following. If antigen is present, a visual pattern forms ('•' or '+') in the test window.

Lyophilized reagents are stable for eighteen months at room temperature. Liquid reagents require refrigerated storage (2-8 C).

Latex Agglutination

The latex agglutination test is most commonly used for screening large numbers of patients. It is an affordable alternative to newer one-step testing techniques although it does not provide the same sensitivity or accuracy and must be performed by trained technicians.

Test kits include a reusable slide and liquid reagents. Liquid reagents have a shelf life of twelve months and require refrigerated storage (2-8 C).

Hemo-PacK & Hemo-Stix

The Hemo-Pack and Hemo-Stix Fecal Occult Blood Tests utilize the Sierra Cassette and Sierra Strip devices together with a specially designed fecal collection tube.

The tube contains a special buffer that is mixed with fecal sample preparing it for testing. The mixture is added directly to the test device and results are read within minutes.

Rapid Swab Test

The biochemical swab test is a new, highly accurate qualitative enzymatic assay. Conducted on the tip of a Dacron swab, test procedures are extremely simple. Obtain a specimen sample using the test swab, add a few drops of the required reagents, and read the results within minutes. Positive results are visually determined by a purple color development on the tip of the test swab.

Kits come complete with swabs and reagents. The shelf life is twelve to eighteen months and refrigeration is required (2-8 C).
