I'm not in charge of POCT, but have heard about this issue today from our POCT coordinator. Since they were used in clinical settings and were never really CLIA-waived, they've sent out this recall and CAP has already issued a memo that our chief pathologist received. Since then the blue cartridges were never FDA approved or CLIA-waived ( even though Abbott stated otherwise) for testing because they weren't demonstrating well with ongoing studies, some facilities were performing poorly with 6 month correlations and Abbott didn't bother to seek FDA approval. Abbott eventually made a modification to them which created the blue cartridge in 2015. “Bone hypercalcemia – intermed mag” By Nephron – Own work ( CC BY 3.Did you see the recall with Abbott's iStat blue cartridge recall? I think it mostly applies to capillary collection, but our hospital/system is disbanding the use of iStats until further notice to be on the safe side.Ībbott had a white cartridge for the iStat BMPs that were FDA approved and CLIA-waived before the blue cartridges. “Calcium regulation” By Mikael Häggström (Public Domain) via Commons WikimediaĢ. “Calcium Blood Test: Normal Range, High, Low.” Healthline, Healthline Media, Available Here Image Courtesy:ġ. “Ionized Calcium Test: Purpose, Procedure & Risks.” Healthline, Healthline Media, Available HereĢ. The main difference between ionized calcium and serum calcium is the form of calcium measured in each test. Both tests are important to diagnose various types of disease conditions.
#IONIZED CALCIUM ISTAT FREE#
In comparison, serum calcium includes both free and bound calcium in the blood. Therefore, they are not readily available. Some of the calcium in the blood may bind to anions and proteins. Ionized calcium is the amount of calcium freely available in the blood. Higher levels of ionized calcium may indicate hyperparathyroidism while lower levels of serum calcium may indicate hypercalcemia. Higher levels of calcium is another difference between ionized calcium and serum calcium. This is another difference between ionized calcium and serum calcium. Lower levels of ionized calcium may indicate hypoparathyroidism while lower levels of serum calcium may indicate hypocalcemia. The normal level of ionized calcium is 4.64 to 5.28 mg/dL in adults while the normal level of serum calcium is 8.6 and 10 mg/dL. Performing the TestĪnother difference between ionized calcium and serum calcium is that ionized calcium test requires special handling of blood samples and it is rare while serum calcium test is easy to perform and it is common. Significanceįurthermore, ionized calcium is the most active form of calcium in the blood while serum calcium includes both free and calcium bound to anions and serum proteins. Thus, this is the main difference between ionized calcium and serum calcium. Ionized calcium refers to calcium in the blood that is not attached to proteins while serum calcium refers to the total amount of calcium in your blood.
Generally, calcium is the cation responsible for the strength of bones and teeth. Therefore, ionized calcium is the most effective form of calcium which is readily available for cells. In other words, these calcium ions are not bound to any anion or protein in the serum. The ionized calcium is the amount of calcium freely available in the blood. – Comparison of Key Differences Key TermsĬalcium Amounts in Blood, Hypercalcemia, Ionized Calcium, Serum Calcium, Thyroid Disease
What is the Difference Between Ionized and Serum Calcium What are the Similarities Between Ionized Calcium and Serum CalciumĤ. – Definition, Reference Levels, Importanceģ. Also, calcium bound to anions and calcium bound to proteins are the other tests that measure calcium amounts in the blood. Ionized calcium and serum calcium are two types of measurements of calcium in the blood. Furthermore, ionized calcium is the most active form of calcium in the blood while serum calcium includes calcium bound to anions and proteins and free calcium amount in the blood. The main difference between ionized calcium and serum calcium is that ionized calcium is the amount of free calcium in the blood whereas serum calcium is the total amount of calcium present in the blood.
