Specimen Requirements
| Patient Preparation: |
An 8-12 hour fast is not required, but is recommended. Indicate patient's fasting status on order request form. |
| Container Type: |
Optimal: Gold or Mint* *For STAT requests |
|
Acceptable: Red or Green |
|
| Optimal Collection Volume: |
4.5 mL; full tube |
| Specimen Minimum Volume: |
|
| Collection Instructions: |
Gently invert sample 5-6 times after collection. |
| Specimen Transport: |
Refrigerate |
| Processing Instructions: |
1. If serum, allow the sample to clot for 30 minutes. 2. Centrifuge specimen within 2 hours of collection. 3. After centrifugation, specimen tubes without a gel barrier should have the serum or plasma aliquoted to a false bottom container. 4. Keep serum/plasma refrigerated until testing can be performed. |

Note on Ionized Calcium
Ionized Calcium is sensitive to pH changes, and is affected by the following conditions:
- Exposure to air - Samples should remain capped
- Prolonged exposure to metabolically active cells - Samples should remain cooled. Gel tubes should be spun as soon as possible.
Specimen Rejection Criteria
| Hemolysis | Mild OK; Moderate OK; Gross Reject |
| Lipemia | Mild OK; Moderate OK; Gross Reject |
| Icterus | Mild OK; Moderate OK; Gross Reject |
| Other | Quantity not sufficient |
Useful For
Routine health monitoring or patient monitoring while hospitalized for information regarding metabolism, including the current kidney status, electrolyte, and acid/base balance, and blood glucose levels.
Methodology
- NA, K, CL - Potentiometric, indirect ion-selective electrode
- CRET and CO2 - Enzymatic
- GLUC - Enzymatic with hexokinase
- ICAL - Amperometric
- BUN - Kinetic test with urease and glutamate dehydrogenase
