Abstract
A carrier tube system and method for using the same includes a carrier tube that is configured to receive a capillary blood tube, and a cap which seals the carrier tube to isolate the blood in the capillary tube from the surrounding atmosphere. The carrier tube system can be placed in a centrifuge which separates the blood with its component parts and optically reads the resulting layer thicknesses. The cap of the carrier tube can include a gear portion which is adapted for engagement with an indexing mechanism of the centrifuge, so that the indexing mechanism can rotate the carrier tube system about its longitudinal axis during centrifugation, thus allowing the optical reader of the centrifuge to take layer thickness readings at various positions about the circumference of the capillary tube. The cap can also include a float holder which holds a float that is inserted automatically into the capillary tube when the cap is placed

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
