المعادل ت الحسابية لبعض التحاليل الطبية Hb conc. = (Normal Hb X Calculated HCT) / Normal HCT Hb % adult male = Hb * 6.4 Hb % adult female = Hb * 6.6 Hb % child = Hb * 6.9 Hb = Reading x 36.77 = ……gm. X 6.9 = ……Hb% . Hct= Hb* 3+1 Ht = Hb(gm) x 3.3 = ……% MCV = [ Ht / RBC's ] x 10 = ……Fl (femto liter) MCH = [ Hb(gm) / RBC's ] x 10 = ….Pg (Pico grams) MCHC = (Hb / HCT) X 100 Reticulocyte (%) = (Number of Reticulocyte / Number of RBCs) X 100 Reticulocyte (%) = ( مجموع عدد الخلايا الموجودة فى الفيلم لعشرة 100 * مجموع عدد كرا ت الدم الحمراء لعشرة حقول/… = حقول.% Reticulocyte index = Reticulocyte count X (Patient HCT / Normal HCT) corrected Reticulocyte count= retic% X patient Hct/normal HctAverage normal hct is 45 for men and 42 for women. Transferrin saturation (%) = (Serum iron level x 100%) / TIBC Unsaturated iron-binding capacity ( UIBC ) = Total iron-binding capacity ( TIBC ) – iron Normal range Transferrin saturation (%) male = 20 – 50 % Normal range Transferrin saturation (%) female = 15 – 50 % LDL mg/dl = cholesterol – HDL – ( Triglyceride /5 ) and if cholesterol and triglyceride are high use another equation: LDL mg/dl = cholesterol – HDL – ( 0.16 * triglyceride ) VLDL=TG/5

To determine the 24 hour urinary protein, measure the 24hour urinevolume in ml and assay the urine for protein content (g/l) as perprocedure. Calculate the 24 hour urinary protein using the followingformula : Protein (g/24h) = urinary Protein (g/l) x TU/1000 Where TU = 24 hour urine volume in ml and 1000 = Converts ml/day to litre/day Calculated Free Calcium ( ionized calcium ) in mmol/Litre i) % Protein bound = 0.8 x Albumin (g/L) + 0.2 x Globulin (g/L) + 3 ii) Calculated Free Calcium (mg / d l ) = T o t a lcalcium – Protein bound Calcium iii) Calculated Free Calcium i n mmo l / L i t r e =Calculated Free Calcium (mg/dl) x 0.25 Or ionized calcium =( total ca _ Alb + 4) / 2 Or ionized calcium = ( total ca * 6 – t.protein / 3) / t.protein +6 Normal range of calcium = 8.8 – 10.5 mg/dl Or 2.2 – 2.55 mmol/l Corrected calcium(mg/dl) = serum calcium(mg/dl) + 0.8 (4 – serum albumin(g/dl)) OR Corrected Calcium ( mmol/L) = Calcium (measured, mmol/L) + {(40 – albumin (g/L)) x 0.02} calcium (mmol/L) = Calcium (mg/dL) x 0.25 albumin (g/L)= Albumin (g/dL) x 10
