LK Packaging 6 x 9 Red Lab-Loc® Reclosable Specimen Bags, 2 Mil
LK Packaging’s 6 x 9 red Lab-Loc® reclosable specimen bags provide high-visibility red containment for serum and chemistry specimen transport with 2 mil LDPE 3-wall construction, an integrated document pocket, and a reclosable zipper closure. Red specimen bags align with the red and gold-top serum separator tubes used for comprehensive metabolic panels, immunology, and endocrinology testing.
What chemistry tests require red-top tube collection and red bag transport?
Red-top tubes without anticoagulant and gold-top SST serum separator tubes are used for comprehensive metabolic panels, lipid panels, thyroid function, hormone levels, immunology panels, and serological testing. Pairing these tubes with red Lab-Loc® bags creates visual alignment between collection method and transport container, supporting correct centrifugation and aliquoting routing at the receiving lab.
How does 3-wall construction protect serum separator tubes during transport?
SST tubes are sensitive to excessive agitation and inversion, which can disrupt the gel separator layer before centrifugation. The 2 mil LDPE 3-wall Lab-Loc® bag construction helps hold tubes upright within the specimen chamber when placed in a transport carrier, while the document pocket prevents paperwork from shifting and pressing against tube caps — minimizing pre-analytical errors for serum chemistry specimens.
Red specimen bags for reference lab send-out serology and immunology testing
Physician office labs sending red-top serology specimens for ANA, RF, complement, and ANCA panels to reference laboratories can use red Lab-Loc® bags to create visual identification for the receiving lab’s intake staff. LK Packaging’s red Lab-Loc® bags support send-out programs where color coding helps route incoming specimens from multiple practice locations to the correct laboratory department.
Do red Lab-Loc® bags provide secondary containment for specimen courier programs?
Yes. LK Packaging’s 6 x 9 red Lab-Loc® bags provide primary specimen containment meeting OSHA bloodborne pathogen and DOT/IATA Category B transport packaging requirements. The reclosable zipper prevents accidental opening during courier transport, and the 2 mil LDPE construction withstands the temperature cycling and physical stress of refrigerated courier and pneumatic transport systems.
