Your blood glucose is awfully low and you’d definitely be symptomatic if that was your real reading at the time. I’m a Paramedic and I’ve had patients with a blood glucose that low still appear fairly normal with the only complaint being weakness. Most other people, I would assume that specially non diabetics, would be very symptomatic with a blood glucose of 39 (I.e. confused, diaphoretic, incoherent, weak etc.)
