Abstract The effect of serum-clot contact time on laboratory results was studied by dividing each blood specimen into four blood collection tubes. The control sera were separated from the clot within 30 min of the collection. The other tubes were incubated at 32 °C, and the sera were separated at 3, 6, and 24 h. The sera were stored at 4 °C and analyzed at the same time. The stability of the tests was determined by comparing the results of the 3-, 6-, and 24-h samples with the values from the 30-min samples. The acceptable limits around the 30-min values were derived from the analytical and intraindividual biological variation of the tests. A total of 63 analytes were studied. Potassium, phosphorous, and glucose were the least stable, and the serum should be separated from the clot within 3 h for these analytes. Albumin, bicarbonate, chloride, C-peptide, HDL-cholesterol, iron, LDL-cholesterol, and total protein should be separated within 6 h. The other analytes were stable for 24 h of serum-clot contact.

Laboratory Record

Abstract A punched-card system was developed to simplify the administrative aspects of the clinical chemistry laboratory. In it a three-part requisition and samples are matched and given a laboratory number. The third copy of the original laboratory requsition is a charge card also used as a name file for the day. Prepunched cards, coded for laboratory tests, are used for each test requested. The laboratory number is stamped and punched on each test card. All test cards are then sorted into laboratory test groups, after which the laboratory data and results are recorded on them. Cards are then sorted for laboratory number and rematched with the original laboratory requisitions, which remained in numerical order. Results are then copied directly onto the requisitions. The system is more efficient, less susceptible to error, and simpler than other laboratory record systems.

Intravenous Fat Emulsions

The Committee on Nutrition, American Academy of Pediatrics has recently reported on the "Use of Intravenous Fat Emulsions in Pediatric Patients" (Pediatrics 68:738, 1981). The committee recommends restriction of the amount of fat emulsion given infants because of a lack of accurate and appropriate means of monitoring serum fatty acid and triglyceride concentrations. Such is not the case for triglycerides. The pediatric clinical chemistry laboratory has the ability to measure serum triglyceride concentrations to support hyperalimentation therapeutic monitoring.

Abstract We evaluated the Abbott Bichromatic Analyzer-100 (ABA-100) for use in the routine clinical chemistry laboratory by examining 13 different determinations that can be performed on the instrument. Results with the Du Pont "aca" and Technicon continuous-flow systems were compared to the ABA-100 in terms of upper limits of linearity, inter-run coefficient of variation, and results for samples from patients. The upper limits of linearity for the methods on the ABA-100 exceeded all of those for the continuous-flow systems, except for urea nitrogen. Precision of the ABA-100 was as good as or better than that of the aca for all determinations, except for glucose in a normal control serum and creatine kinase and creatinine in an above-normal control serum.
