“…Lipemia may cause erroneous PLT (see part I) and WBC counts (see above), but may also induce interferences by turbidity (Creer & Ladenson, 1983;Sandberg, Sonstabo & Christensen, 1989). An abnormally high MCHC (>36 g/dl) corresponding to an erroneously high Hb has been reported for patients with severe constitutional or acquired hypertryglyceridemia (Gagne et al, 1977;Mayan et al, 1996), and for patients receiving intravenous administration of fat emulsions (Nosanchuck, Roark & Wanser, 1974;Shah, Patel & Rao, 1975;Nicholls, 1975Nicholls, , 1977Creer & Ladenson, 1983;Artiss & Zak, 1987;Sandberg, Sonstabo & Christensen, 1989;Cantero, Conejo & Jimenez, 1996). After the study of various types of hyperlipoproteinemias, it was observed that erroneous Hb and MCHC >36 g/dl were observed in patients with at least 20 g/l of triglycerids, corresponding to type I and part of type V hyperlipoproteinemias (rich in chylomicrons) but not to type IV hyperlipoproteinemias (rich in very low density lipoproteins; Gagne et al, 1977).…”
