Urine Specimen Stabilizers for Delayed Testing

Cult-Ur™ Tablets

Stabilize Urine Specimens For Delayed Laboratory Examination of Urine

Maintains Bacterial Viability at Room Temperature Up to 72 Hrs.

• Eliminates refrigeration of urine culture specimens during storage
  or transit.*
• Prevents over-growth of U.T.I. bacteria in specimen.

Maintains Normal Growth and Chemical ID Characters of U.T.I. Bacteria

• Culture and Subculture growth characteristics are not altered.*

Minimizes Growth of Patient Introduced Contaminants

• Accidentally introduced contaminants won't confuse results because levels are maintained for at least 24 hrs.
• False positives are virtually eliminated reducing the need for a second sample, and preventing needless patient anxiety.

Convenient To Use

• No messy or strong smelling liquids to dispense into tubes

Cult-Ur™ Tablet Price Schedule

The Cult-Ur™ Tablets are formulated for effective bacteriostatic action without altering the viability of typical urinary tract bacteria for culture and identification (no fluorides).

Stabilur® Tablets

Stabilize Urine Specimens For Delayed Laboratory Microscopic Examination of Urine Sediment

Maintains* Red and White Blood Cells in Original Condition

• Prevents the usual rapid lysis of leukocytes to assure accurate confirmation of this key indicator of urinary tract infection.¹
  
• Permits accurate counting and estimation of erythrocytes

Maintains* the Morphology of Typical Formed Elements in Urine Sediment Such as Casts, Crystals and Mucous Threads

• Morphology and staining characteristics of casts and cells are retained in original condition.
• Tablet dissolves completely and does not contribute any crystals to the sediment.²

* Protects unrefrigerated specimens circa three days.

Maintains* Most Urine Dipstick Chemistries

• Maintains most chemical constituents in urine for retesting by dipstick chemistry by preventing bacterial decomposition.
  
• Does not interfere with enzyme based dipstick chemistry tests, i.e. leukocyte esterase.³

  At recommended levels urine pH is buffered to just under neutral, and specific gravity is raised 0.002.
  

*Maintains Other Chemistry Assay Components

• Does not interfere with certain TLC and RIA methods for assay of physiological marker compounds and drugs and their metabolytes.

Stabilur® Tablet Price Schedule

The Stabilur® tablets contain a proprietary mixture of buffering and osmolality adjustment ingredients, plus agents which produce a minute quantity of several bacteriostatic chemicals sufficient to prevent bacterial degradation of urine constituents, without interfering with most analyses. Shelf life is 5 years from date of purchase.

1. Depending on osmolality and pH of the urine, up to 90% of unstabilized leukocytes are lysed in as little as 2.5 hours at elevated room temperature. Even at 4 degrees C, 50% may be lost in that time.
2. Wait until the tablet has completely dissolved before centrifuging the sample (approx. 30 min. +).
3. Validated on Ames (Division of Miles Laboratories) and Boehringer Manheim chemistry dipsticks: November, 1986.
