Self-Swab for STI Testing

Self-collected vaginal swabs may be used for STI testing testing as opposed to provider-collected swabs. Self-collected swabs are supported by current clinical guidelines as recent studies have shown their equivalence, if not superiority, in quality and their association with increased patient satisfaction.

NOTE: Self-collection must still take place in a healthcare setting and is not approved for at-home collection.

CSF Xanthochromia Result Update

Effective February 24, 2021, Cerebrospinal Fluid (CSF) Xanthochromia results of “Present” will be considered a critical laboratory value.

This change was approved by the MEC and driven by a collaboration between neurology and laboratory departments to assist in expediting the diagnosis and management of patients with possible subarachnoid hemorrhage (SAH).

The following disclaimer will also be attached to all Xanthochromia results: “Xanthochromia is assessed by visual inspection. If the appropriate history and symptoms are present, CSF xanthochromia is suggestive of subarachnoid blood, either as part of an inflammatory reaction such as meningitis, or after subarachnoid hemorrhage (SAH). Xanthochromia must be viewed within the appropriate clinical context.”
