Introduction

When to activate the clot-detection feature

To activate the clot-detection feature Clot-detection process

Analyzer messages

A new feature is included in software version 6.06 of the following products:  ABL7xx Series (XPE) analyzers  ABL800 FLEX analyzers  ABL800 BASIC analyzer. The new feature enables the analyzer to detect clots caught in the measurement chamber under the pH electrode. This document describes it. It is especially beneficial to activate the clot detection feature in analyzers frequently used to analyze samples known to be prone to clotting, for example, samples drawn from umbilical cords. Once activated clot detection is active during all sample measurements. NOTICE: It is important to note that activating the feature will delay measurement results by approximately one minute, even though it only increases the measurement cycle time by five seconds. It also increases consumption of Rinse solution, but this is minimal. Contact a Radiometer representative and request that clot detection be enabled via the service program.

During calibration the measuring chamber is rinsed and the pH of the Rinse solution is measured. The value is stored in the analyzer. During a sample measurement the measuring chamber is also rinsed and the pH of the rinse solution is measured and compared with the pH value stored during the last calibration. If the difference between these values (the pH drift) exceeds a pre-determined maximum value, it could indicate the presence of a clot beneath the pH electrode. When enabled, the clot-detection feature can generate three new messages that are listed below. NOTICE: Operator actions are listed in order of priority. Perform the first action in the list and the actions indicated in the "Removal condition(s) list. If the message persists, perform the next listed action and the actions indicated in the "Removal condition(s) list, and so on.

Names and intended use Names

Intended use

Proprietary name:

ABL800 FLEX blood gas, oximetry, electrolyte and metabolite analyzer.

Common name:

Blood gas, oximetry, electrolyte and metabolite measuring system.

The ABL800 FLEX analyzers are intended for: •

•

In Vitro testing of samples of whole blood for the parameters pH, pO2, pCO2, cK+, cNa+, cCa2+, cCl–, cGlu, cLac, cCrea, ctBil, and co-oximetry parameters (ctHb, sO2, and the hemoglobin fractions FO2Hb, FCOHb, FMetHb, FHHb and FHbF) in vitro testing of samples of expired air for the parameters pO2 and pCO2

The following parameters can be measured on blood: Parameter group pH/blood gas:

Parameters pH (acidity) pCO2 (carbon dioxide tension) pO2 (oxygen tension)

Oximetry:

ctHb (total hemoglobin concentration) sO2 (oxygen saturation) FO2Hb (fraction of oxyhemoglobin in total hemoglobin) FCOHb (fraction of carboxyhemoglobin in total hemoglobin) FHHb (fraction of deoxyhemoglobin in total hemoglobin) FMetHb (fraction of methemoglobin in total hemoglobin) FHbF (fraction of fetal hemoglobin)

Electrolytes:

cK+ (potassium ion concentration) cNa+ (sodium ion concentration) cCa2+ (calcium ion concentration) cCl– (chloride ion concentration)

Metabolites:

cGlu (D-glucose concentration) cLac (L(+)-lactate concentration) ctBil (concentration of total bilirubin, measurement in plasma is possible, see Limitations of use later in this chapter) cCrea (concentration of creatinine, measurement on plasma and serum possible, see Limitations of use later in this chapter) Continued on next page

1. Introduction

Names and intended use, Continued Intended use (continued)

The following parameters can be measured on expired air samples: Parameter group Measured values

Parameters pCO2 (carbon dioxide tension) pO2 (oxygen tension)

Derived parameters are listed in chapter 13: Specifications and described in detail in the Reference Manual, chapter 6. Requirement to the operator

The analyzer should be used by personnel who have received special education and training with regard to procedures utilizing in vitro diagnostic medical devices.

Measurements Animal blood has not been tested on the ABL800 FLEX analyzer. Some on animal blood components in animal blood differ from those in human blood, and variations in the composition of blood from different animal species may also exist. FLEXMODE

This mode allows you to analyze a blood sample of 35 μL and higher – up to the maximum volume accepted by your analyzer. Depending on the available sample volume, the FLEXMODE provides the highest number of parameters: from all available to as many as reliably possible. This mode is not available in the ABL8x7 FLEX analyzers.

Other fluids mode

All parameters available on your ABL800 FLEX analyzers can be measured on fluids other than heparinized human whole blood NOTE: Before using this mode you must establish "user-defined corrections" for each parameter used, on the fluid in question. The corrections assume a linear correlation between the measured value and the reference instrument. The data used for establishing "user-defined corrections" have to cover the desired measuring range. If no user-defined corrections are entered, you will measure in this mode as if on heparinized human whole blood.

FLEXQ module The FLEXQ module can accommodate up to three samplers simultaneously. It reads a sampler's barcode, mixes the sample and transports the sampler to the inlet for aspiration and analysis without any further assistance from the operator. Results can be delivered via FLEXLINK (for information refer to the RADIANCE Installation and Setup Manual). NOTE:

The model ABL810 can also be ordered without oximetry parameters: as ABL810 BG only.

1. Introduction

ABL800 FLEX Operator's Manual

Limitations of use and known interfering substances Limitations of use

The following limitations should be taken into consideration: The ABL800 FLEX analyzers are designed for measurements of adult and fetal hemoglobin with normal spectrum characteristics. Some spectra deviate from the normal characteristics, e.g. for certain hemoglobinopathies and the ABL800 FLEX analyzers do not compensate for this. WARNING/CAUTIONs: • The user should review the analyzer performance data to assure that the performance fulfills the user-specific analytical needs. • The validity of the test results from this instrument must be carefully examined by a clinician and related to the patient’s clinical condition, before any clinical decisions are taken on the basis of the test results. • Bilirubin measurements on plasma and creatinine measurements on plasma and serum need to be measured in Other fluids mode, as the other modes are intended for measurement on human whole blood only. Corrections for Creatinine can be found in the Reference Manual. • WARNING - Risk of erroneous results. Always meticulously follow the sampling procedures described in Chapter 12: Sampling. Failure to follow these procedures may introduce clots or air bubbles in the sample and yield erroneous results. FHbF measurement: The uncertainty in FHbF measurements exceeds the level required to measure normal HbF levels in the adult range (FHbF reference range is 0-1 %).

Known interfering substances

The following substances are known to affect or interfere with measurements on the ABL800 FLEX analyzers. Substance

Interference

Halothane (anesthetic)

May give unreliable pO2 results.

Lipid therapy (treatment)

In OXI measurements. After measurement on blood from a patient who has received lipid therapy it may be necessary to clean the analyzer using the Cleaning program.

Methylene Blue, HiCN (medication)

In OXI measurements.

Anions: Br − , I − , S 2− and ClO 4− (drugs)

Erroneously high cCl- results.

ABL800 FLEX Operator's Manual

1. Introduction

Limitations of use and known interfering substances, Continued

Known interfering substances (continued)

Substance

Anticoagulants (sampling)

Interference

Anticoagulants that contain sodium salts will give erroneously high cNa+ results. Sodium fluoride with or without EDTA and oxalate (di Na) influence cGlu results. Sodium fluoride gives erroneously high cNa+ and low cCa2+, cGlu and cLac results. Tri sodium citrate influences cNa+, cK+ and cGlu results. Thus Radiometer recommends the exclusive use of heparin as anticoagulant. Solutions containing organic preservatives may damage the ion-selective membranes of the cK+ and cGlu electrodes when introduced into the analyzer. Do not use EDTA, as it leads to erroneous pH, pCO2, cNa+, cK+ and cCa2+ results. Use of EDTA will also affect subsequent measurements on the cCa2+ electrode and it will reduce the lifetime of this electrode.

Erroneously high cGlu and cLac Thiocyanic acid (degradation product from treatment with measurements. nitroprussid. Also produced in thiosulphate treatment of cyanide poisoning) Glycolic acid (ethyleneglycol degradation product)

Erroneously high cLac measurements.

Insufficiently stabilized blood. Caustic fluids (e.g. strong acids or bases, detergents, etc.). Fluids that precipitate. Fluids that affect the sensor enzymes. Fluids that form complexes with the analyzer solutions (calcium). High viscosity fluids. Hydrophobic fluids. Reactive fluids.

Other fluids mode allows you to measure on fluids other than heparinized human blood. WARNING/CAUTION: Be aware that some substances, such as listed in the left column, measured in the Other fluids mode may damage the instrument or the electrodes. This can affect the subsequent measurement on human blood or quality control solutions.

Limitations of use and known interfering substances, Continued

Known interfering substances (continued)

Substance

Interference

Carboxymethyl cellulose (CMC) Some auto-venting arterial blood samplers contain carboxymethyl cellulose (CMC) in the porous vent. CMC can dissolve into the sample and give erroneously low cCa2+ results. Therefore we recommend Radiometer accessories together with our analyzers, e.g. the safePICO arterial blood sampler which is specifically designed to minimize sample contamination with CMC. Galactose, glucosamine, maltose, Erroneously high cGlu measurements. mannose, xylose
