As An Adjunct to Hemoglobin A1C Interpretation
Findings of recent studies have identified the existence of a linear relationship between Hemoglobin A1C (HA1C) and average blood glucose levels.
The formula used to determine this value is:
28.7 X A1C - 46.7 = eAG mg/dL
Effective July 5, 2010, Clinical Laboratories of Hawaii will begin reporting eAG automatically with all HA1C test orders. This is done at no additional cost and is offered as a convenience for you and your patients. |

Urine GC/Chlamydia Collection for Females only
Due to strict guidelines specified for optimal urine GC/Chlamydia collections on females it is unacceptable to use the same specimen for clean-catch urinalysis testing. Female patients should NOT use the cleansing wipe because it has a higher likelihood of causing testing failures. In addition, we have validated the test for GC/Chlamydia in female urine, but only with these additional restrictions:
• Patient should not urinate up to 2 hrs prior to collection. Spermicidal agents and feminine powder sprays can interfere. Do not use prior to specimen collection.
• Collect 15-50mL of the FIRST part of a voided urine; i.e, not mid-stream. Anything above 50 mL and the organisms in the specimen may be too diluted to detect. Anything less than 15 mL and there may not be enough organisms present in the specimen to detect.
• Void into a sterile cup.
*** SUBMIT THE ENTIRE URINE CUP *** or note the total
volume of the entire voided urine on the aliquot tube. |

| Colorectal cancer (CRC) is the second leading cause of cancer-related deaths. About 147,000 new cases are diagnosed each year, which has prompted the American Cancer Society to promote screening tests for adults over the age of 50. Even so, there are 41 million Americans who have not been screened for CRC. ...(more...) |

CLH IS CHANGING RH TYPING PROTOCOL
NO LONGER TO ROUTINELY TEST FOR "weak D" (formerly Du)
It had been customary to perform weak D (Du) testing to detect whether a patient who was D negative upon initial testing might carry a weak expression of the D phenotype not picked up by the D typing reagents in use at that time. Those individuals testing positive for weak D were classified as D Positive. ...(more...) |

Random Urine Total Proteins (UTP) will now include the creatinine and UTP/creatinine ratio!
In an effort to make the results for random urine total protein more meaningful and useful, CLH will automatically be performing the creatinine in order to provide the UTP/Creatinine ratio. Since creatinine excretion in the urine is fairly constant throughout the 24 hr. period, calculation of the total protein/creatinine ratio allows correction for variations in urinary concentration that occur throughout the day. ...(more...) |
